The question of how long past the period you can have intercourse without getting pregnant is very much related to when the patient gets her period and how many days she gets her period. If you have a period in about 28 days, you can have intercourse for 5 days and within 5 days after your period without getting pregnant. This is because a woman’s ovulation period is 14 days before her next menstrual period, and it is generally more dangerous to have intercourse within 5 days before and after, and the rest of the time you will not get pregnant. So if a woman has a long period and her menstrual cycle is short, she may get pregnant if she has intercourse after her period clears. So there is no fixed time for this, it depends on each patient’s individuality.
