An Honest Review of Kegg

The kegg device draws a fertile window to give you the best days for conceiving a pregnancy based on the electrolyte levels present in the vagina. To use this device, someone would insert kegg into the vagina in the same two hour period of time during the day. kegg takes approximately two minutes to give the user a reading on the graph. As a bonus, it also gives you the opportunity to do kegel exercises while using it. Click here to read an article on the science behind kegg.

This product is an exciting development in the femtech field because it actually does read a real-time fertility sign. Cervical mucus is completely necessary for natural conception to occur. Without the presence of cervical mucus in the cervical crypts, sperm cannot to get to their destination to reach the egg. For this reason, anyone trying to conceive needs to track cervical mucus or use an alternative device such as Kegg (or a device that reads estrogen levels) in order to time intercourse for when they are most likely to conceive.

My kegg values compared to my Billings Ovulation Method cervical mucus observations. I believe that the kegg was highly correlated with my actual fertile window based on a traditional fertility awareness based method!

Who is Kegg right for?

It is important to know that kegg is not suitable for avoiding pregnancy. It is designed to find the most suitable days for conception. For those avoiding pregnancy, the fertile window has to be much longer than the window what the kegg gives. Until kegg has been studied for pregnancy avoidance, I cannot recommend it as an alternative to cervical mucus checks which must be made multiple times of day until the evening when someone is strictly avoiding pregnancy.

kegg may be right for someone who wants to conceive without needing to take a class or read a book on cervical mucus. In my experience, for the most part, it detected my most fertile days in a way that would likely lead to conception if used.

kegg may not be right for you if you have a very erratic schedule. Because it has to be used in the same two hours and cannot be used up to 8 hours after sex, this may make Kegg harder to use.

One Cycle Seven Ways: Experimenting with Marquette (Clearblue Monitor), Billings Method, Sympto-Thermal, Daysy, Kegg, DOT, and more!

Over the last several months, I have been testing multiple femtech products (such as Daysy Fertility Tracker, Kegg, DOT) and comparing them to charting methods like Marquette, Billings Ovulation Method, and Sympto-Thermal (NFPTA). These products and methods rely on different fertility signs such as basal body temperature, cervical mucus, urinary hormones, electrolyte levels, and calendar dates.

Disclaimer: Do not attempt to learn to chart using this post. My own experience may not reflect your unique cycles. My fertility intentions may not be your intentions.

Keep in mind that different methods may change safe days over time. The following data is only a snap shot of what fertility windows for avoiding pregnancy could look like. In particular, the Daysy thermometer only has 4 cycles of data on me.

Expected Consecutive Abstinence Over 3 Cycles

Cycle 52

Billings Ovulation Method: 15 (9 consecutive)
Marquette: 13
Sympto-thermal: 16
DOT: 12
Daysy: 15

Cycle 53

Billings Ovulation Method: 14 (8 consecutive)
Marquette: 13
Sympto-thermal: 13
DOT: 12
Daysy: 14

Cycle 54

Billings Ovulation Method: 16 (9 consecutive)
Marquette: 15
Sympto-thermal: 19
DOT: 12 (EXTREMELY RISKY)
Daysy: 15

From this data, you can see that sometimes the amount of expected abstinence does not differ from method to method, and sometimes it differs a whole lot! On my last cycle with DOT, it ended my avoidance window on the day after peak fertility occured. Fertility is still potentially high on the 3 days following this date.

Billings method almost always had the least consecutive abstinence because it relies on real-time fertility signs to open the window. However, because it rejects calculation rules and relies on one primary sign, only alternative evenings are ever allowed for pre-ovulatory sex. In addition, heavy days of menstruation are not allowed due to the possibility of early ovulation, and the bleeding obscuring the opening of the fertile window.

Other methods like Daysy, Sympto-thermal, DOT, and Marquette do allow pre-ovulatory consecutive sex, but most of that falls during menstruation for my cycle ranges (25 to 30 days).

Whatever method works best for someone is very dependent on their lifestyle and what someone is willing to diligently track.

The Same Chart Seven Ways

The highlighted days represent days to not use in order to avoid pregnancy with these methods.

My hearts are left on to show the fertile window and for authenticity. Do not use these charts to try to learn the rules of any method or to determine when sex is safe. You will see some broken rules based on my own personal intention level and on the fact that not all fertility signs will show the same window.

The Billings Ovulation Method draws the fertile window based on vulva sensation and cervical mucus. Any heavy bleeding is considered potentially fertile because it obscures readings and ovulation can always happen early. It requires alternating evenings for sex during the established basic infertile pattern.

This is the Marquette Method while using only urinary hormones and calculation rules. Fertile window opening determined by calculation rule based on last 6 cycles or first “H” reading on the Clearblue monitor. Clearblue measures estrogen and luteinizing hormone. My first window is also closed by a progesterone test in addition to meeting PPHLL rules.

This is the double-check sympto-thermal method per Natural Family Planning Teachers Association (NFPTA) rules. It opens the fertile window based on the shortest cycle in the last year minus 20. It closes the fertile window based on cervical mucus and basal body temperature.

This is a chart with the Daysy Fertility Tracker. This basal body thermometer learns your patterns over time and opens the fertile window based on past cycle data. The fertile window changes with time, and this is technically my 3rd Daysy cycle. Caution days and Red X days are for avoiding intercourse. Daysy does not allow the user to mark temperatures questionable, but I have marked two days questionable because I drank alcohol or had the heater on.

This example chart includes my cervical mucus notes for more context. DOT is a calendar based method that looks at the last 12 cycles of data. Only people in regular cycles can use DOT. Black moons are days available for intercourse based on the calendar method. In the next line, I also have included Kegg. Kegg predicts ovulation for trying to conceive purposes only, so I am including it as a bonus comparison. By reading the electrolyte levels in my cervical mucus, it determined that these 3 days were the most fertile days of the cycle. A full Kegg review is forthcoming in December 2020.

This is a resting heart rate chart. Resting heart rate has been shown to correlate with the menstrual cycle. I convert my heart rate like this: 69 = 96.9, 70 =97.0, 71 = 97.1, etc to be able to fit it onto the graph. You can see that it very closely followed my ovulatory pattern.

Here is my chart with all the data in one. It is so cool how different fertility signs draw the fertile window!

Unfortunately, my Mira Fertility sticks were flawed, so I had to remove that data from this experiment. In the future, I will do a comparison post also using this device. I am currently still testing the Kegg device, and a review with full Kegg charts is forthcoming in December. Kegg cannot be converted to display on the Read Your Body app, so I could only include the fertile days in this post.

Shortcut charting, or “Wait… I don’t have to take my temperature every day?”

Many people come into FAM overwhelmed by all the data that they have to collect daily. It can be a bit of a turn off for those new to the method. They may wonder why they have to check their cervical mucus ALL day and then set an alarm on top of that.

When you first begin charting, it is vitally important to try to get the information down every day so that you can get into a habit and make sure that you are following the rules. Missing information will leave you with less complete charts that could leave you confused as to whether ovulation is confirmed or not.

However, once you have been charting for a significant amount of time and become confident, you can stop recording fertility signs once you have confirmed ovulation.

I am headed into chart number twenty-two successfully avoiding pregnancy with FAM, and I have been shortcut charting most of the time for about seven cycles now. I personally recommend confirming ovulation in 12 cycles before shortcut charting. This is so that you know how early you ovulate, your normal temperature levels, and how to tell whether something abnormal is going on in your cycle (ie sickness causing temperatures to be higher than normal or an abnormal cervical fluid dry up due to cold meds or some other medication).

Toni Weschler, author of Taking Charge of Your Fertility, recommends that women have several months of experience in the standard rules before taking any shortcuts. She offers some modified guidelines to follow and emphasizes that “contraceptive efficacy won’t be compromised as long as both your fertility signs have confirmed that ovulation has already been confirmed for that particular cycle.”

The Modified Rules

Temperature Taking

You don’t have to take your temperature during your period. Toni explains that these temps may be unreliable anyways. However, if you have short cycles with early ovulation, you may need those temps in order to confirm ovulation. If you have a temperature shift CD12 or sooner, you will need some period temps in order to have enough temperatures to draw a coverline.
You don’t have to take your temperature after you confirm ovulation with temperature rules. This means at least 3 high temperatures with a standard shift. If you have weak shift or a fall back rise, you must have the extra temperatures needed to fulfill those rules before you stop taking your temperature. Some people take their temperature again a day or two before they expect their period since it can (but not always) give an indication that menstruation is approaching.

Cervical Mucus

You don’t have to check cervical mucus after you confirm ovulation. You will need to check until you meet peak rules (P + 3) and crosscheck this with 3 high temperatures before you can stop checking for cervical mucus. Again, if you have a weak shift or fallback, you will need to check until you meet the rules.
From the day after your period until the day you observe peak type fluid, you should check cervical mucus continuously throughout the day and follow all rules for mucus checks. However, you don’t have to check cervical mucus multiple times a day once you observe peak fluid. If you observe peak fluid first thing in the morning, there is no need to keep checking. You have already recorded your most fertile observation for the day.

Those are the basic changes when short cut charting.

Here is an example chart.

This woman does not take her temperatures during her period. She begins taking her temperature on CD6 when menstruation ends. She checks her cervical mucus multiple times a day and follows the rules for checking until CD11. On CD11, CD12, and CD13, she observes eggwhite mucus first thing in the morning and doesn’t check again. On CD14-CD17, she checks mucus multiple times a day because she knows she needs at least a 3 day dry up (P + 3) to confirm ovulation. On CD 15, she has her temperature shift. CD16 is above the coverline. CD17 confirms ovulation because it is at least .4 F above the coverline. Ovulation is officially confirmed with both peak and temperature rules met. She takes her temperature again on CD26 to see if she gets a temperature drop indicating that her menstruation may begin soon.

People Who May Want to Think Twice about Short Cut Charting

Not everyone is suited to short cut charting.

Charting for Health: If you are charting for health, you may want to record your signs every day. Odd cervical mucus patterns and temperatures can indicate health issues. If this is your goal for charting, short cut charting may not be right for you.
Using Tempdrop: Tempdrop says to wear the device every day. If you don’t, it could disrupt the algorithm. As far as I know, they do not recommend short cut charting at this time. If you use this device, you may not want to short cut chart if you are worried about being at risk of pregnancy.
You aren’t confident in charting: If you are not confident in your ability to chart, you should NOT short cut chart. You should be 100% confident in your abilities before attempting this.
You are sick: If you are sick, you may want to chart more diligently and stay protected if you are uncertain about your chart interpretation.
You are only charting one sign: You NEED two signs in order to short cut chart. If you pick just one, you may be putting yourself at risk of unintended pregnancy. Ovulation must be confirmed with two signs.

An Honest Review of Tempdrop

Are you looking to simplify your basal body temperature charting routine? Is getting up in the morning just too hard to remember to take your temperature? Read on!

There are currently a few wearable basal body thermometers on the market such as iFertracker, Ava, and Tempdrop. In this blog, I will review the Tempdrop device. If you decide to purchase, use this link and get 10% off the device. This discount only works on the Confidence and Freedom Packages.

Tempdrop is a wearable basal body temperature thermometer that came onto the market in 2017. Rather than setting an alarm, you can simply put this thermometer on before bed. You wear it around your upper arm (and it may be worn in a bra as well). It needs 3 hours of sleep to determine your basal body temperature. The device uses an algorithm to find your true temperature, regardless of how many times you have gotten up or whether you had restless sleep this night.

This device is very popular with shift workers, breastfeeding mothers, and other people who don’t get a regular amount of sleep and wake up at different times. It holds 24 hours of data, and it must be synced at least every 24 hours or you will lose previous data. After wearing it for 15 days (as of March 2020), the algorithm will kick in. (If possible you should back up temp with oral basal body temperature for the first 60 days if you are avoiding pregnancy. If not, use a different method of protection). By day 60, the device will only change and make improvements to the last 2 temperatures taken.

PROS

Helps Women Practice the Sympto-Thermal Method: If you are not able to take your temperature with a normal basal body thermometer due to breastfeeding, shift work, or other irregular sleep schedules, this device will help you practice any sympto-thermal method of fertility awareness or natural family planning.
Great Customer Service: I have had to interact with Tempdrop Customer Service several times. They are fairly prompt with responses, and they do try their best to troubleshoot with you. While there was an issue with the Tempdrop frame breaking, they fixed this issue for free.
No Alarm Needed: Hate your alarm? You won’t need to set it to take your temperature if you wear Tempdrop. This is a big game changer for people with irregular sleep schedules. It can make your mornings much easier.
Helpful Facebook Group: You may join the Tempdrop Facebook group for support and charting help. They have detailed units about how to use this device to achieve or avoid pregnancy. There are multiple spin-off Tempdrop groups that you may want to explore as well.

CONS

Price: Tempdrop Basic Package is $159 (12 month warranty). Tempdrop Confidence Package is $199 (12 month refund guarantee, 24 month warranty, Tempdrop Care available). Tempdrop Freedom Package is $249 (24 month warranty, Tempdrop Care, 12 month refund guarantee, extra armband and battery). While this price could be worth it for you if it’s the only way you can take your temperature, it may not be affordable to everyone. This price is still a little high, especially if you are making minimum wage or have other expenses like childcare. The referral codes only work with the higher price packages (scroll to the end of this to get 10% off the device). If you have kids or animals, you may want to get a better package if you believe your device may be damaged easily.
Battery: The device does not tell you when the battery is dying. However, you can contact support to find out. They now recommend changing the battery at 8 months.
Frame Breaking: Many people (myself included) have had the frame break easily. However, the company promises that they are trying to fix this issue and a newer frame with different plastic will be issued with devices bought this year.
Changing Temperatures: If you are the anxious type, you may not like the last few temperatures changing. While this is due to the way the device functions, some people may find it unsettling. Second, many people who chart expect that they will see a drop in their temperature before they get their period or the day of. I personally never got the drop to indicate my period was coming until Tempdrop retroactively adjusted my last temperature. With oral basal body temperature, changing temperatures is not a problem.

In 2020, Tempdrop released their own app. I do NOT recommend using it to interpret your data for you. It is quite expensive, and it does offers to interpret your data for you. The best app is one that lets you make all the decisions instead of forcing you into certain rules that may not fit your chosen method.

Here is an example of the Tempdrop app:

Source: Google Play Store

Instead, I recommend using Read Your Body app which is only $15 USD a year and empowers you to read your own fertility signs! It automatically syncs with Tempdrop. This is my top recommendation if you are determined to use Tempdrop for avoiding pregnancy. It is entirely customizable down to the cervical mucus categories and incredibly diverse custom data. See my blog on using this app for 7 different types of fertility methods and devices.

My Original Experience with Tempdrop in 2018

I used the Tempdrop device for almost 12 months. I found my oral temps to be more predictable and more steady when observing my own trends over time. I get very steady or repeating temperatures with oral charts most of the time.

However, I am not a shift worker, so I will admit that I do not need Tempdrop like some people may do. I already have to wake up at the same time 5 days a week, and I don’t find it inconvenient to take my temperature on the weekend. Even if I take my temperature later, my oral temperatures are incredibly steady. My oral temperatures also caught my shift earlier than Tempdrop did on two separate occasions (I have seen other people say that Tempdrop catches their shift sooner than oral temperatures, so this is really an individual thing).

Funnily, alcohol appears to effect my Tempdrop temperatures MORE than my oral temperatures. I speculate that this is because whenever I would put the Tempdrop on, I was still recently drinking and hotter due to the alcohol. In contrast, I would be sleeping for 8-9 hours and have worn off the alcohol before taking my oral temperature.

Here is one full cycle comparison:

Tempdrop (Ovuview)

Oral Temperatures (Kindara)

Tempdrop temperatures will either read higher or lower than your oral temperatures. In my case, they read much higher.

Why Fertility Awareness Can Be a Feminist Choice

In this blog, I’m going to refute some of the arguments against fertility awareness. At the risk of losing some of my audience immediately, I have included the word feminist in this blog title. A while back, I got into an argument in a Facebook comment section with someone who was offended by this article that questioned the pill and it’s effect on women. The argument went nowhere fast, but it got me thinking.

In many circles, questioning the birth control pill is tantamount to attacking women’s rights. I have been told that I’m not a good feminist if I don’t support the pill. As someone who fully supports women and their choices, and as someone who only wrote about women in my graduate degree (I did a lot of gender studies topics), this assertion really hurts.

I know that the birth control pill changed many people’s lives. It brought women into the public sphere more than ever before. Women could now work and have sex without fear of pregnancy. It is considered a great achievement. What’s better than that?

The problem is that not many women are not fully informed about what their birth control options are before being put on the pill. In addition, women are put on the pill for reasons other than birth control (things like heavy bleeding, endometriosis and PCOS). However, we now know there there are alternative forms of birth control, and that the pill does not treat gynecological conditions (it masks them).

I was put on the birth control at age 15. I suffered from heavy bleeding, and mostly my mom just wanted me on it out of pregnancy fears. My doctor did not give me any information about the pill or expected side effects. (Some may point out that the packet comes with information, but freshman year aged me from high school did not think to read my birth control pack in depth). I was switched between at least 4 different types of birth control that I remember. The pill gave me migraines with aura (which I recently learned means I should have gotten off of it immediately, there is a link with having a stroke and migraines with aura while on the pill). I would lose vision while at work and had other disturbances in my vision. I also had pretty regular nausea, weird bleeding, depression, and digestive issues.

When I came off the pill for the first time at age 21, everything felt different. My emotions felt different, and my relationships changed. However, I was left with little alternatives for contraception. To me, taking the pill had become synonymous with being responsible, and I felt like I was failing at being a responsible woman and controlling my fertility.

At the same time, I felt so great coming off of it that I knew it wasn’t an option for me any longer. I felt truly like myself for the first time. One line in particular from a short film called Birth Control Your Own Adventure really resonated with me. This film is about how one woman struggles to find the right hormonal birth control. At one point a friend asks her, “How do you even know who you are if you’ve always been on the pill?” And, truly, I don’t think I knew myself while I was on it.

In my search for a better birth control, I stumbled upon fertility awareness methods. I found out that it was possible to track my cycle and determine daily whether I was infertile or infertile. Charting my cycle helped me learn when to expect a period. I had no idea that you could literally count high temperatures after ovulation in order to know when to expect a period. This feeling felt revolutionary, and I wanted to tell everyone.

When I try to share the joy I have found in this method, I often hear a few retorts. I’ve listed a few below along with my responses to these arguments.

The Arguments Against Fertility Awareness

Why should I have to plan sex? It seems kind of sexist that you expect women to wait to have sex at certain points in their cycle. On the pill, I can have sex whenever I want.

With fertility awareness methods, you don’t really have to “plan” to have sex. You can, however, choose to have unprotected sex during the infertile times of the cycle. If you are using a secular form of fertility awareness, you can also use condoms or other barriers during other points of the time in the cycle (keeping in mind that these barrier methods have their own efficacy rates).

I think it’s also worth noting how often the average couple has sex. A 2017 study found that the average American couple only has sex once a week. My window for abstaining or using backup protection is only about 9-11 days long. That’s a little over a week and a half a month. (I’m aware that some women have longer fertile windows. This aspect of fertility awareness is very individual and based on your own unique cycle). So, are these women really missing out on having unprotected sex a little less often?

Finally, yes, you can have sex on the pill whenever you want. However, the pill has been known to lower women’s libido and testosterone. Read this article to find out more. So, while you can have sex any time you want on the pill, doesn’t quality of sex matter? You can still have sex pretty often while using fertility awareness, and you may find you enjoy it more too.

This method seems really irresponsible. It only takes one time for a woman to get pregnant. What if she decides to have sex in her fertile window?

If someone is fully informed and taught by an instructor, they will know when their fertile window is. Yes, it only takes one time to get pregnant but if you are using fertility awareness, you know when that window is. If she decides to have sex in her fertile window, she may consider a barrier method. Anyone who has sex during their fertile window should be cognizant of the risks of pregnancy. By the way, at a typical use rate of 91%, someone could also have sex in their fertile window without knowing it while on the pill. At least fertility awareness lets women know what is going on in their own body.

Isn’t that a super religious method? I don’t care for that. It’s my body and I can have sex when I want.

Natural Family Planning is based in religious teachings. Fertility Awareness is not. Women can pick what they feel comfortable with based on their intentions. You can also still learn from NFP resources even if you aren’t religious. The method works the same regardless of any ideology attached to it.

Isn’t that like the rhythm method? You can ovulate at any time!! That’s not gonna work!

No, it’s not. There are many scientific studies on fertility awareness. Here is one. Here is a recent article reviewing all the studies done on FAM.

Women cannot ovulate at any time. Once ovulation has been confirmed in cycle, it is almost totally impossible for it to happen again. Some people say, “What about superfetation??” This is so rare, and almost impossible to prove. If you are confirming ovulation with a double check method, then you can be safely assured that ovulation will not happen again. At the beginning of a cycle before ovulation is confirmed, it could happen at any time. However, there are rules to follow so that women know when to stay protected.

The typical use rates of fertility awareness (when abstinence is practiced in the fertile window) is higher than the typical use rate of the pill. See my about section for more information.

But women need the pill for medical conditions, you know like endometriosis? Do you want women to suffer?

Obviously, I don’t want that. What’s important to know here is that the pill doesn’t actually treat endometriosis, or PCOS, or anything else really. It just masks the problem. If you have extreme period pain, you need expert care. The pill may mask problems that would eventually hurt a woman’s health and fertility. In particular, I want to note that if you are suffering from endometriosis, there is help. Join Nancy’s Nook Endometriosis Education to learn what your options are. For PCOS, Alissa Vitti is a great resource. Here is her website.

Isn’t it kind of anti-feminist of you to promote this? Women should be able to control their fertility however they choose.

Ah, my favorite question. I do agree that women should be able to control their fertility however they want. My whole shtick is that they should be fully informed in order to make this decision. With the dearth of good sexual education programs in the USA, almost no one is informed enough. Even doctors aren’t informed enough. Many only take one measly birth control class. Fertility awareness instructors do more than that, and they aren’t even in medical school. If more women knew that fertility awareness methods actually worked, they could make the decision to learn more about their body. I believe that all women should learn about fertility awareness methods as soon as they have their first cycle. It is so useful for girls to know what’s going on in their bodies!

I also argue that we have a #righttoovulate. I saw Dr. Lara Briden post this hashtag a while back, and I love it. Ovulation is amazing. And actually, I think it’s sort of anti-feminist to take that away from women, especially if they don’t understand what they are missing. Women are only fertile for around 24 hours a cycle (men’s sperm life makes up the rest of the fertile window). This is such a small window. Don’t we deserve the benefits of ovulation? Read Dr. Lara Briden’s article, “Ode to Ovulation” to learn more. In addition, some people have argued that it takes 7 years to develop fully healthy hormonal cycles, shouldn’t we be able to do that too? Putting women on birth control when they are young prevents so many of those benefits.

**I will note that I understand that hormonal birth control can be invaluable in domestic violence situations, or when a woman really cannot do FAM, or is forced on HBC for unrelated medical conditions. I just want the average woman to know that she has other options.

Conclusion

Most of the arguments against FAM are from uniformed people who don’t know what they don’t know. Fertility Awareness is actually feminist, and it’s certainly not anti-woman. It allows women to take control of their own fertility (here’s a great book on that). What’s more feminist than fully owning and living in your own body, while also avoiding pregnancy and planning it as you choose? Why should women subdue their own fertility when their fertile window is so short?
