Is it possible to get pregnant on your period? I had sex on my period and was taking the white sugar pill for my birth control. I wanna be pregnant so bad again but I'm forced to take birth control because my mom doesn't want any more Grand kids and as long as I'm under her roof I have to take it. I'm 21 .-. I'm trying to get pregnant but it's hard on the pill.. I'm hoping for an "accidental" pregnancy.
