It's a relatively simple way to know when you're ovulating, because eggs can only survive in a woman's body for about 48 hours. Therefore, if you want to get pregnant, it is very important to know when you are ovulating.

A woman's menstrual cycle usually ranges from 28 to 35 days, but most women have a 28-day cycle. On day 14 of the cycle, a woman's eggs begin to mature and reach their peak around day 16 of the cycle. Around this time, women may feel some discomfort on one side of their abdomen, which is pain left over from the process of egg maturation and expulsion.

Therefore, if you want to know when you are ovulating, you can start recording your body temperature on day 14 of your cycle. Usually, a woman's basal body temperature will increase by 0.3 to 0.5 degrees every morning until the 16th or 17th day of the cycle. Around this day, a woman's eggs may reach their peak and may begin to be released.

By recording body temperature and knowing when ovulation occurs, women can better predict when they are likely to become pregnant. In addition, if the woman releases an egg on the 14th or 15th day of the cycle, and the man ejaculates into the woman on the 16th or 17th day of the cycle, pregnancy is possible.
