There are many ways to check ovulation, one of the simplest methods is to check the ovulation period by counting the day of menstruation. Ovulation refers to the date when a woman's egg is released from the ovary, usually between the 14th and 16th days of the menstrual cycle.

Another method is to use body temperature measurement to check ovulation. Every morning when you wake up, take your temperature and record it on a chart. During ovulation, body temperature usually rises by 0.3 to 0.5 degrees Celsius.

No matter which method you use, checking your ovulation period is very important. If you plan to have sex, make sure you do it during ovulation to ensure sperm can enter the woman's body and combine with the egg.

If you are not sure how to check your ovulation period, it is recommended to consult a doctor or professional consultant for more detailed advice and guidance.
