It is possible that ovulation has happened if your basal body temperature rises higher than the temperatures you have reported in the previous six days and remains at this amount or increases for at least three days. In general, after ovulation, the temperature range is at least two-tenths of a degree higher than your temperature during the previous week between 97 and 99 degrees.

What are the pros and cons of using a basal thermometer?

A simple thermometer is cheap and quick to use on the positive side. It’s a low-intervention approach of having a basic understanding of how the loop functions.

In order to get an accurate reading, you must take your temperature before getting out of bed, talking, eating, drinking, having sex, or smoking. The basal thermometer should be inserted for a full five minutes, and within one-tenth of a degree, the reading should be recorded.

What is a BBT chart and how does it work?

A BBT chart tracks fluctuations over the course of several months in your basal body temperature (BBT) that occur within your cycle. A slight increase in signals from your BBT that you have ovulated.

This can be helpful but also subject to technical and incorrect information glitches (a 2019 study published in the Journal of Obstetrics and Gynaecology Canada evaluated 140 menstrual- and fertility-tracking iPhone apps and found that 31 of them had serious inaccuracies).

What Is Basal Body Temperature (BBT)?

The lowest body temperature within 24 hours is indicated by basal body temperature (BBT) . Now at any given moment when you feel colder, you can not just measure this. It has to be the first thing you do when you wake up in order to get a proper reading.

Your last measured temperature is tracked by the thermometer, so whenever you like, you can record it on your chart. It is an actual thermometer for body temperature, not a predictive thermometer. That means, as the probe adjusts, it may take longer, but it will produce the most accurate reading. A free table of charts is available for download.

Recommended Basal Thermometers

A basal body temperature (BBT) thermometer is needed when using the Symptothermal Method of Fertility Knowledge. A BBT thermometer is a very sensitive thermometer that measures up to two decimal places accurately. This is important because it can be as small as 0.2 ° C for the changes you are looking to identify during the charting. The lowest core body temperature achieved during rest is your basal body temperature, and it usually occurs around 4 am in the morning. Since most of us don’t want to wake up every morning at am, a few hours later, we take our waking temperature instead. Most women orally take their temperature, while others may choose to vaginally take their temperature. You need to make sure that when searching for a thermometer: you buy a BBT thermometer that measures accurately to two decimal places You buy a BBT thermometer and not a standard fever thermometer (although many standard fever thermometers display two decimal places, they do not measure accurately enough to be used as a BBT thermometer).

The iSnow Digital Basal Thermometer The iSnow, at just over $25, is a great step up from the Mabis. It has a backlight to prevent you from squinting or turning on a light early in the morning. It also has an internal memory that can store 60 temperatures, which means that you do not need to immediately record your temperature – you can return to it later that day or in 60 days! Last but not least, it has an alarm clock built in and is also available for secure storage in a large, robust case. The Vinca II Femometer The Vinca II Femometer is a premium choice and is very suitable for Symptothermal Process charting. It is best to grab their Vinca II model that includes a screen to see your temperature (earlier models required you to sync the thermometer with their app to see your temperature each day).

In addition to this for the duration of the time it will evaluate your BBT, the Vinca II allows you to choose from three different options: 1.) Fast Mode (30 seconds) 2.) Normal Mode (1-1.5 minutes) 3.) Mercury Mode (3 minutes) Mercury Mode is particularly beneficial as the formal rules of many Symptothermal Methods require at least a 3-minute evaluation of your BBT each morning. You can also change the beep frequency either up or down with the Femometer Vinca II, plus you can store up to 300 temperatures. The Tempdrop Smart Thermometer The Temprop is a fantastic femtech piece! It is a wearable device that takes your temperature multiple times throughout the night (worn on the upper arm in an armband).

In order to inform you what your actual basal temperature is at night, it then sends certain temperatures into an algorithm. For shift workers (hello doctors and nurses!) and postpartum/nursing mothers who tend to have very fragmented sleep, this means it’s a fantastic option. Read more about Tempdrop here and discover a $10 discount code. The Wink Digital Thermometer The Wink thermometer (by the founders of the Kindara app) is no longer in production; you can still find one second-hand for sale sometimes however. Originally, this thermometer was built to sync directly with the Kindara app to enter your temperature quickly. While this sounds user-friendly and very convenient, as the design is flimsy and many users report that it breaks easily, I don’t recommend the Wink. I would pick a Tempdrop instead if you’re on the lookout for a second-hand BBT thermometer! Wink – flimsy, and no longer in production. The Daysy/Ladycomp/Babycomp Devices

These devices were previously heavily marketed on social media and YouTube, explaining that they used the devices as contraception by paid influencers. The devices were marketed by Valley Electronics AG (the manufacturer) as 99.4 percent productive with perfect usage to reliably predict the fertile window based on temperature alone. The real efficacy of the Daysy/Ladycomp/Babycomp devices remains, unfortunately, unknown. Due to a number of fatal flaws that meant the final figures were unreliable, their most recent study was withdrawn from the scientific literature. Learn further on the retraction here, which was finalized after a peer-reviewed commentary highlighting the study’s shortcomings was released by leading sexual health epidemiologist Chelsea Polis.

Furthermore, their recent report promising a 99.3 percent productivity score of ideal usage has also been dismissed as inaccurate. Valley Electronics AG (aka Daysy) does not take criticism kindly and does not have the best track record of transparency with its customers as a personal anecdote. In fact, Daysy continued to advertise their device as 99.4 percent effective during the entire year that it took for the journal Reproductive Health to retract the 2018 Koch paper. In this situation, their profit pursuit was placed above the right of their clients to accurate and up-to-date information about the device they were buying. The continued support this company receives from high-profile figures within the FABM and natural health world is also concerned.

His verdict? Use yourself at your own risk. If I were to pick between Daysy and Natural Cycles, I will choose Daysy, since their algorithm appears to be much safer (despite the lack of quality research to support it). Here you can read more about why I don’t personally recommend these devices: 5 Reasons I Don’t Use Daysy or Natural CyclesDaysy – True efficacy remains unknown. Natural Cycles Natural Cycles is an app that claims to predict your fertile window based on temperature alone with 93 percent accuracy (with typical use). My humble view is that if you seriously wish to prevent a baby, utilizing Natural Cycles is risky.

Anecdotally, not a week goes by that I don’t see women during their fertile window reporting unplanned pregnancies or being given green days. In addition, the app’s founder (Elina Berglund) and one of the leading scientists behind the studies of Natural Cycles (Kristina Gemzell) were both cited as saying that this app is not a good option for women who are seriously trying to prevent pregnancy. You can read more about the reasons why I don’t recommend Natural Cycles personally here: FDA Approval of Natural Cycles: What’s The Big Deal? Natural Cycles – if you are really trying to prevent pregnancy, a dangerous option. Ava Woman Cycle Tracker Bracelet The Ava is a bracelet that tracks wrist skin temperature, pulse rate, breathing rate, heart rate, sleep, and more. It is designed to help those who are trying to conceive and is NOT approved by those who are trying to prevent a pregnancy as a method of contraception or for use.

Some women decide that they want to use the temperatures provided by their Ava bracelet, and combine them with a graph of cervical mucus. For two reasons, this is not advised: wrist temperatures have not been proven to be sufficiently accurate for use with FABMs. Through an algorithm that is based on other metrics such as breathing rate/heart rate and more the temperature readings that Ava provides are modified or smoothed. It is therefore not precise enough to be used as part of an FABM. If you’re trying to imagine that you’re better off learning to monitor your cervical mucus and cervix, these are physiological signs that actually warn that ovulation is approaching. If you are trying to get pregnant, BBT and heart rate only increase after ovulation – which is usually too late to be of any use. On top of that the statistics currently used by Ava are based on a small study of only 41 females, each with one menstrual cycle.

The verdict on Daysy, Natural Cycles and Ava?Ava – in the same class as Daysy and Natural Cycles. They are overpriced thermometers, in my view, which can put unconscious users at risk of unintended pregnancy. I don’t think they’re delivering real value for money. Bear in mind that interacting with a teacher to practice Fertility Knowledge is often better – an educator would be able to lead you on both the nuances of taking your temperature correctly and the basic laws to validate your temperature change. They would also be able to help you build a good awareness of the cervical fluid, too. An teacher can be located here.

What’s basal body temperature?

When you’re sleeping, basal body temperature defines the temperature. When you’re ovulating, your basal body temperature will minimally rise. In the two or three days due to this rise in temperature, women are at their most pregnant.

What Is a Basal Thermometer?

A basal thermometer is very close to a traditional thermometer which functions very closely. They are far more adaptive, though, and can also calculate smaller shifts in the BBT. A traditional thermometer, for example, can give you a 98.2 degree Fahrenheit reading. In the other side, the basal thermometer will read 98,235 degrees Fahrenheit, bringing you more decimal positions and thus a more detailed reading.

Features of BBT Thermometers

Any features that add importance do include specialty BBT thermometers. Memory retrieval is also present in optical BBT thermometers. This ensures that the temp may not have to be registered first thing in the morning. To get the last registered temp, you can only toggle the thermometer back on.

Beurer ovulation thermometer

The symptothermal technique is a clinically accepted method of natural family planning that allows natural family planning simple (NFP). Fertile days, and the basal temperature, are calculated using physical signs. Using the ‘Ovy’ software, you will capture all the relevant stuff.

This thermometer is a well-rounded choice with an alarm clock, sensitivity to 1/100th of a degree, period day monitoring, and graph population for your 10 prior readings. It would also allow you to interpret the readings of your thermometer so you can forecast fertility correctly.

BBT Thermometers to Avoid

Read any feedback before purchasing, not because of the fertility characteristics, but because certain inexpensive optical thermometers don’t last long or don’t have screens that are simple to read. (If you do not have memory recall functions and need to read it at dusk in the morning, this is important.) Some BBT thermometers come with sample charts. Thermometers that are very pricey will monitor the temperature on an internal machine for you. These attributes might or may not be regarded by you as a waste of resources. It depends on how familiar with charting you are.

BBT Thermometer Options

If you’re not ready to acquire a new thermometer right now you may be able to get away at home on everything you have. However these simple body thermometers are fairly priced and have decent features if you wish to purchase a new one.

Why it’s done

By helping you gauge the right days to have or stop casual intercourse, basal body temperature may be used as a means to predict pregnancy or as part of a form of contraceptive. It is economical to monitor the basal body temperature for either fertility or contraceptives which has no side effects. For religious purposes, certain women may opt to use the basal body temperature form.

Hot or Not?

One of the best ways to think about the period is to monitor your Basal Body Temperature. First thing in the morning, it is important to take your temperature, without any activity beforehand. To have the greatest performance, it should also be at the same time of day.
