Ovulation is a critical stage of pregnancy because at this time, a large number of eggs are released from the female body. These eggs will survive in the body for about 3-5 days and then be absorbed by nature. Therefore, getting pregnant during ovulation is the best option.

In addition to measuring body temperature, we can also judge by observing the menstrual cycle. Generally speaking, a woman's menstrual cycle lasts about 28 days. In the middle of the cycle, a woman's body temperature will rise, which is usually during ovulation.

In addition to measuring body temperature and observing the menstrual cycle, we can also use other methods to determine ovulation. For example, basal body temperature can be measured or determined using a calendar.

Getting pregnant during ovulation is the best option, so we should use as many of these methods as possible to determine when we are ovulating and have sex during this period.
