How long does it take for menstruation to occur during ovulation?

Generally speaking, a woman's menstrual cycle lasts about 28 days, and ovulation occurs between the 14th and 19th days of the menstrual cycle. This is because it takes 6 to 8 days for a woman's eggs to mature and be fertilized after they are released. Therefore, between the 14th and 19th days of the menstrual cycle, the eggs are most active.

However, everyone's menstrual cycle is different, so the specific ovulation period also varies from person to person. In addition, women's menstrual cycle will be affected by many factors, such as mood, stress, diet, exercise, etc.

Therefore, if you want to get pregnant, it is best to calculate a woman's ovulation period based on her menstrual cycle and have sexual intercourse during this period to increase the chance of pregnancy. However, a woman’s menstrual cycle will vary from person to person, so if you have any concerns or questions, it’s best to talk to your doctor or professional advisor.
