Basal body temperature is the body’s temperature while resting. During ovulation, BBT rises slightly. Tracking BBT over several months can help a person predict when they will ovulate and most likely to become pregnant.
A female is
If a person wants to get pregnant, they can monitor their BBT for several months to understand when ovulation usually occurs within their menstrual cycle. A person may plan to have sex during their most fertile period to increase the likelihood of pregnancy.
This article explains what BBT is and the reasons for detecting it. It also discusses a female’s most fertile period and how to predict it using the BBT method.
BBT is the lowest body temperature that occurs after rest. In most people, a change of
If a person wants to use the BBT method of temperature mapping, they have to measure their temperature at the same time every day, first thing after waking up. It is important to measure the temperature before getting out of bed, eating, drinking, having sex or doing anything else.
There is around
BBT is usually lower in the days before ovulation. After ovulation, it will rise and rise again within 24 hours.
A person can record their daily readings on a graph to easily detect differences. The temperature changes are very slight, so a thermometer measuring up to at least tenths of a degree is the most accurate method.

When are you most likely to get pregnant?
A person’s menstrual cycle begins on the first day of menstruation and usually lasts about 28 days, although it can vary between 21-40 days.
Ovulation occurs approximately
A male’s sperm can live
When are you least likely to get pregnant?
Once ovulation occurs and the ovary releases an ovum, it has 12–24 hours for sperm to fertilize it before it dies or the body reabsorbs it. After this time, it is less likely to prevent pregnancy until the next menstrual cycle.

For most women, 97–98 ° F (36.1–36.6 ° C) is a typical pre-ovulation BBT. After an ovary releases an ovum, BBT rises.
During ovulation, BBT will increase by an average of 0.5–1 ° F to 97–98 ° F (36.1–36.6 ° C) and remain higher until the end of the menstrual cycle. A female’s most fertile days are 2-3 days before BBT rises.
By tracking their BBT over several months, a person can identify patterns that will help them predict when they will ovulate and optimize their chances of getting pregnant.
It can be challenging to interpret a BBT card first. A medical professional or family planning clinic can help with this.
The BBT method is not completely reliable for the following reasons:
- BBT indicates when ovulation has already occurred, so it may not be an effective method to predict when it will happen. For this reason, a person should not use this method to prevent pregnancy or birth control.
- A person should take their BBT lectures at the same time every day, before getting up and before eating, drinking or doing anything else. If they deviate from this regime, it can affect their body temperature.
- Other factors can affect body temperature and make it difficult to spot patterns and predict ovulation.
- drinking alcohol or smoking cigarettes the night before
- insufficient sleep
- do anything before taking a BBT reading after waking up in the morning
- the calibration and accuracy of the thermometer
A person must measure their body temperature
To measure BBT, a person can use a digital or BBT thermometer that measures in tenths of a degree.
A person can record each day’s reading on a graph. It can be on paper, an application or online. Once a person has detected a few months of BBT readings, they can study the pattern to identify the time in the cycle when their BBT rises.
An increase in BBT indicates that ovulation has already taken place, so a person may try to determine sex on the days before the temperature rise occurs for the best chances of getting pregnant.
Taking a BBT requires a thermometer that measures up to tenths or hundreds of a degree. Many are available as digital thermometers, or a person can purchase a special BBT thermometer.
Below are examples of thermometers:
- iProven: It reads up to 1/100ste of a degree within 60 seconds. It does not synchronize with an application, but the user can enter the information manually in any application or on a paper card.
- Easy @ Home: It measures up to 1/100ste of a degree in Celsius or Fahrenheit within 90 seconds. It features a large, illuminated screen and stores up to 30 temperatures. Users can download an application to track temperatures, but must enter it manually.
- Feminine Vinca I: It measures up to 1/100ste of a degree and synchronize readings automatically with an application. This thermometer has an alarm to wake you up with an adjustable volume.
- She cares: It measures up to 1/10ste of a degree in 90–120 seconds and synchronizes with the Shecare application. This thermometer can store 400 measurements.
- Mabis: It reads up to 1/100ste of a degree and comes with a 12-month supply of paper ovulation cards for tracking. It has a large screen and an alarm tone when reading is complete.
BBT is the lowest temperature that occurs after rest. During ovulation, a female’s BBT increases slightly.
Tracking BBT over several months can indicate when ovulation usually occurs within a person’s menstrual cycle. If an individual wants to get pregnant, they can plan to have sex during their most fertile days.
External factors can affect BBT, such as drinking alcohol, smoking, illness, or not taking an immediate BBT reading when you wake up.
To take BBT readings, a person can use a digital thermometer that measures up to tenths or hundreds of a degree.
