What Is The Basal Body Temperature?
Basal body temperature is the lowest temperature your body may reach when at rest. Your basal body temperature is more stable and trustworthy than the average body temperature collected during the day. Typical body temperature may be taken at any time and is variable owing to physical activity, food consumption, emotional state, and environmental factors. Basal body temperature is recorded first thing in the morning before getting out of bed, eating, drinking, or participating in any activity.This is why checking your basal body temperature is so important for monitoring ovulation and fertility. Unlike taking a temperature when you're sick, basal body temperature is measured under very specific conditions to give you insights into your fertility cycle and natural rhythm.
What Is The Normal Basal Body Temperature?
The average daily body temperature is often higher than one's basal body temperature. It typically fluctuates between 97.6 and 98.6 degrees Fahrenheit (36.4 to 37 degrees Celsius) after ovulation and between 97 to 97.5 degrees Fahrenheit (36.1 to 36.4 degrees Celsius) before ovulation.Understanding How Your Cycle Affects Basal Body Temperature?
Your basal body temperature and menstrual cycle are closely related. What occurs at each step is as follows:- Follicular phase: Because of the low amounts of oestrogen and progesterone throughout this phase, which begins on the first day of your period and ends with ovulation, your basal body temperature remains relatively low. Temperature readings typically range from 97 to 98 Fahrenheit (36.1 to 36.6 Celsius).
- Ovulation: Basal body temperature will decrease significantly in the 24 hours before ovulation. A spike in luteinizing hormone (LH) causes ovulation, which is followed by a rise in progesterone.
- Luteal phase: During the luteal phase, which occurs after ovulation and before your period, your basal body temperature rises by roughly 0.5 to 1 degree Fahrenheit (0.3 to 0.6 Celsius) due to an increase in progesterone after ovulation. Your progesterone levels will remain high for approximately 14 days before gradually decreasing, leading your basal body temperature to return to baseline a day or two before your period begins.
- Menstruation: After your temperature returns to your baseline basal body temperature, your period should arrive shortly after. When your menstruation is due, if it stays high, this might be an excellent time to take a pregnancy test.
How To Take The Basal Body Temperature?
Take your basal body temperature using a basal body thermometer. This is a unique sort of digital thermometer that displays two decimal places, and those two decimal places are extremely significant in recording the most subtle variations in your basal body temperature.Take your temperature first thing in the morning, before sitting up or getting out of bed. Aim to monitor your basal body temperature at least five times each week. For a more accurate assessment, exclude days where you did not receive at least three hours of undisturbed sleep.
Place the thermometer orally, vaginally, or rectally, and take the temperature at the same time every day. Using a pen and paper, a basal body temperature monitoring app, or the notes on your phone, you may take your temperature.
Why track it?
Basal body temperature is often lower in the days preceding ovulation. Following ovulation, it will increase again within 24 hours and stay elevated.A person may use a chart to record their daily readings and easily spot discrepancies. Because the temperature fluctuations are so small, the most precise way is to use a thermometer that measures to tenths of a degree.
Factors That Could Affect The Basal Body Temperature
External considerations may impact basal body temperature findings, including:Factors that may affect a basal body temperature reading include alcohol or cigarette use the night before, insufficient sleep, stress, activity before waking up, and the thermometer's accuracy.
Trying To Conceive?
While tracking your basal body temperature regularly, you should watch for moderate dips followed by a rise of roughly 0.5 to 1 degree Fahrenheit (0.3 to 0.6 Celsius). This will allow you to pinpoint your ovulation day because the day before this rise is likely when you ovulated. Identifying this trend throughout several cycles may aid in predicting fertile periods.Other Ways To Monitor Ovulation
If you're trying to conceive, there are several techniques to monitor ovulation. - Ovulation predictor kits: These kits, often known as ovulation tests or strips, detect a rise in LH hormone in your urine before ovulation. A positive test indicates that you are at your most fertile.
- Cervical mucus monitoring: Look for changes in cervical mucus to determine whether you're in the fertile window. During ovulation, your discharge will become "clear and stretchy, like egg whites”.
- Fertility monitoring: Advanced instruments, such as fertility monitors, can analyse ovulation signs like hormone levels in urine, saliva, and vaginal secretions to provide further information about your cycle.
- Tracking physical signs: It's beneficial to pay attention to your body's distinct signals. Some women report ovulation discomfort or heightened desire around ovulation.
Basal body temperature is the lowest temperature reached after rest. During ovulation, a female's BBT increases somewhat.
Tracking Basal body temperature over many months may help determine when ovulation typically happens throughout a person's menstrual cycle. However, do note that BBT is not the most accurate method of planning a pregnancy. If a person wishes to get pregnant, they may schedule intercourse during their most fertile periods.
A digital thermometer with tenths or hundredths of a degree accuracy may be used to obtain BBT readings.
FAQs on How Can Tracking Your Basal Body Temperature Help You Conceive?
- How do I monitor my basal body temperature while trying to conceive?
Your basal body temperature drops 1–2 days before ovulation due to hormone changes. basal body temperature rises a day or two post-ovulation. For a few months, carefully measuring your basal body temperature every morning before getting out of bed and charting it may help you anticipate ovulation. - What happens to the basal body temperature if you conceive?
Continue monitoring after ovulation (until your menstruation starts). If you had conceived that cycle, your basal body temperature would remain high.
