Pregnancy During Period: Understanding the Chances & Ovulation

It is extremely unlikely to get pregnant on your period unless you have an unusually short menstrual cycle. This is because ovulation, the release of an egg from the ovary, typically occurs 14 days before the start of your period. During your period, the lining of the uterus is shed, and the levels of the hormone progesterone, which is essential for pregnancy, are low. These conditions make it difficult for a fertilized egg to implant in the uterus.

While having unprotected sex during any time of your menstrual cycle holds some possibility for pregnancy, it is least likely to occur during menstruation. If you want to avoid pregnancy, it is important to use contraception during sex, regardless of where you are in your menstrual cycle.
