I am on the pill and I missed my period in march. It was suppose to come on march 6-12 but it didn't. Since I have been on the pill I have never missed a period before even if I did miss a pill or 2. I took a pregnancy test and it said negative. Then on march 15 I had unprotected sex with my boyfriend and he didn't pull out. I talked to a nurse and she told me that I would know 7 to 10 days after. So a week later I took a test and it said negative. But also on that same day I started to have these really really bad pains in the bottom of my stomach. The pain was below my belly button. :cry: it hurted so bad that sometimes I couldnt really walk straight. I just laid in the bed and cried myself to sleep. It hurted this bad for 4 days. During those days I noticed that the right lower part of my stomach was swollen. My nipples have been really really sore and sensitive, have gas alot, I burp alot, I have been sleeping alot also and I am I little moody to. When I have my period I am not moody and I don't cramp so when I had those pains I was worried. I am not sure if a pregnant but I am worried.
