Hi!

This is my first time posting on this board and I have a question. I'm on bc pills and I had unprotected sex about 5 weeks ago. Well, about a week after, I started getting really bad cramps (which is weird because it was about a week and a half before my period and I usually don't get them that early.) also I just had this weird sort of feeling in my stomach that I can't explain. Then, I stared feeling nauseous and sick for a few days. I got my period on time and it was normal. But after it's over I still have this weird feeling in my lower abdomen. It feels like on and off cramps sort of. Also, I am sleeping a lot longer than I usually do and I am always tired. And my bbs look bigger and firmer. I was wondering if I could be pregnant? And how likely would that be since I am on bc and I had my period?

Thanks!
