Ovulation refers to the period of time when an egg is released from a woman's body, usually starting on the 14th day of the menstrual cycle and lasting about 4 days. This is very important for women trying to conceive as this is the best time for fertilization.

1. Observe the menstrual cycle

The most common method is to observe the menstrual cycle. A woman's menstrual cycle usually lasts about 28 days, but some women may have cycles of 30 days or longer. If the menstrual cycle is 28 days, then starting from the first day of menstruation, ovulation will be on the 14th day. If the menstrual cycle is 30 days, then starting from the first day of menstruation, the 16th day is the ovulation period.

2. Use a thermometer

A woman's ovulation period can also be measured using a thermometer. Usually, a woman's body temperature will rise by 0.3-0.5 degrees Celsius, especially in the first 4 days and 5 days after ovulation. You can determine your cycle and calculate your ovulation period by recording your basal body temperature every day.

3. Use a calendar

If a woman has a regular menstrual cycle, she can use a calendar to determine when she is ovulating. Plot the dates on the calendar and record the day in each cycle. Based on the calendar, you can calculate your ovulation date and fertilize on that day.

4. Use B-ultrasound

If women want to determine their ovulation period more accurately, they can go to the hospital for a B-ultrasound examination. Doctors can determine a woman's ovulation period by observing changes in the uterus and ovaries and guide fertilization.

Calculating a woman's ovulation period isn't the only way to do it, but these methods can help women better understand their bodies and optimize the time for fertilization. If a woman is unsure about her cycle or wants to more accurately determine when she is ovulating, talk to her doctor or healthcare professional.
