Alright so, I had sex about 16 days ago...I am on the pill and we used many other precautions....i had my period last week and it was heavy. This week i just dont feel like myself but it would be that i am so worried about being pregnant that Im making myself think i am. I have some abdominal pain...but it may be from pushing on it a bit and tonight i went to the bathroom and found brown discharge but it might be because I just ended my period. I also had a severe headache the other day and i feel as if my stomach is bloated or..bigger. I need some help here...does this seem like it could be pregnancy?
