A woman is more likely to get pregnant if she has intercourse around the 9th to 18th day after her period. If a woman’s menstrual cycle is accurate, the average menstrual cycle is 28 days, and the day of ovulation is about 14 days before the next menstrual period. The day of ovulation and the 5 days before and 4 days after it are called the ovulation period, and the probability of getting pregnant is higher if you have intercourse during the ovulation period, that is, from the 9th to the 18th day after the menstrual period. Depending on the individual’s physical condition, some girls’ menstrual cycles are not accurate, but you can also go to the hospital for follicle testing, and if you observe that the follicles are mature, intercourse is also easier to get pregnant. If there is a plan to prepare for pregnancy, couples can choose to have intercourse during ovulation, the probability of pregnancy is greater; if there is no idea of having children for the time being, it is recommended to have sex, all to take contraceptive measures to prevent unwanted pregnancies, resulting in psychological stress. If you have any other questions, you can consult a professional doctor for guidance.
