Small chance: On the 4th day of your period its less likely that you would get pregnant (but not impossible). The "withdrawal" method is fraught with peril. If you don't want to get pregnant, you should get on a more effective method. If you use this method long-term, you will eventually get pregnant. Best wishes!

Even if you do it perfectly every time, you will eventually get pregnant!

Conception optimum: Women ovulate 14 days before their next menstrual period starts. In a 28 day cycle this would be day 14. Male sperm can survive for up to 5 days. If intercourse happens on day 4 of the cycle, conception is unlikely.
