There is no specific requirement for the number of coitus during ovulation in preparation for pregnancy, and it is recommended to have sex on alternate days.
For women with regular menstrual cycles, the 14th day or so before the next menstrual period is the day of ovulation, and from the five days before to the four days after the day of ovulation is the period of ovulation. Women with irregular periods can confirm ovulation by using ovulation test strips.
Every month, a woman releases only one or two eggs on the day of ovulation, and the eggs survive in the body for only about two days. After having sex during ovulation, pregnancy can only occur when the sperm discharged by the man combines with the egg.
However, having sex too often can lead to a decline in sperm quality. To ensure sperm quality, it is recommended that you have sex on alternate days when you are ovulating. To ensure sperm quality, it is recommended to have sex on alternate days during ovulation and try to have sex in the morning or afternoon after getting enough rest.
If the next period does not come on time, you can test whether the pregnancy is successful.
