My boyfriend and I had unprotected sex just before my period he came a lot inside me. I started my period a few days later. Could I still be pregnant? My mom had her period before both my brother and I. So could I be?

Hello,

If your period was normal with normal blood flow and of normal duration, then you cannot be pregnant. The endometrial lining (lining of the uterus) gets shed with the menstrual blood and an embryo, if fertilization occurs, will be shed together with it.
