If the menstrual period is normal, the ovulation day should be 14 days before the next menstruation. The normal ovulation period is between 11-17 days after the end of the menstrual period, but everyone’s physical condition is different, so it should be judged according to each person’s specific situation. If the couple is preparing for pregnancy, they can choose ovulation test strips to not only accurately understand their ovulation situation, but also to better understand the problem of ovulation, and having intercourse during ovulation can not only improve the chance of pregnancy, but also promote the successful implantation of egg cells. It is also important to relax during pregnancy preparation, not to be overly stressed and tired, to get enough sleep, and to replenish your body with the necessary nutrients and vitamins.
