Can u get pregnant when ur on your periods?

Unreliable : Women can get pregnant when they are bleeding especially when the bleeding is not their normal period. Not all vaginal bleeding means they are on their menstrual cycle. Ovulation occurs 14 days before the cycle starts and this is the optimal time to get pregnant. When a true menstrual cycle comes it means fertilization did not occur. Having sex during that time would be low risk for pregnancy.
