I've had unprotected sex with my partner for about two weeks since we ran out of condoms and always forgot to buy some and I'm not on the pill. So when we got condoms back we had sex and when I reached to get the condom off his penis it was inside of me. Anyways, I took the plan b pill 6h after we had sex. Should of got my periods in the beginning of this week, And I feel as if my abdomen is really hard. Is it possible I am pregnant? Since for the two weeks we had unprotected sex it was just the pull out method..
