I got my period a week early while I was still in my month of pills. I stopped taking my bc pull still the following Sunday of the next week. I started a new pack and finished it. It's been a week since I finish my most recent pack and I still haven't had my period. I had sex but we have used a condom. I want to take a pregnancy test but I cramp like I'm going to get my period. Is this normal of not getting a period??
