Under normal circumstances, if you have just stopped menstruating, you will not get pregnant on the same day you have intercourse, because at this time you are still in the follicular stage, the diameter of the follicle is only about 7mm, so it has not reached the dominant state, the follicle can only be expelled to form a fertilized egg with sperm before you can get pregnant. The survival time of the sperm in the woman’s body after intercourse is usually about 3 days, and during the survival period of the sperm, it is often not yet time to ovulate, so the chance of pregnancy is very, very low. However, there is a special case where the menstrual cycle is relatively long, for example, the menstrual cycle is once every 28 days, then the menstruation clears in 9-10 days, in this case, if you have intercourse, there is a possibility of pregnancy. It is advisable to use contraception when having intercourse or to take emergency contraceptive pills within 72 hours after intercourse.
