When a woman is ovulating, she can usually arrange to have sex once or three times so that she can effectively improve her chances of conception. The best time to arrange sex during ovulation is before bedtime. If you have sex at other times, you may not stay in bed for a long time, such as standing up or moving around, which can easily lead to the outflow of semen from the vagina and reduce the probability of conception. Therefore, if a woman is sure to ovulate during the ovulation period, she should usually arrange sex at night before bedtime and pad her hips appropriately, which can effectively increase the chances of conception. For women who are not sure about ovulation, they can use ovulation test strips or go directly to the hospital for ovulation detection through ultrasound.
