Ok I got off my period November 18 & on Nov 21 I had unprotected sex & my bf ejaculated inside of me but later that night I started spotting. But I took the take action pill on Nov 22 but I threw up like a hour or two after taking it. So after that ive been having very small light spotting ever since Nov 22 && now it's been 7 days && I still haven't had my period could I possibly be pregnant???
