I am 18 years old. I don't know if I could be pregnant. I had my period for 6days ended Oct.28, 2014, I had sex for my first time Oct.31, 2014 with my boyfriend and ever since then I didn't get my period, I went to the doctors and they took tests and said I was not pregnant and nothing is wrong. So they put me on birth control on Jan.19, 2015 i forgot to take my pill a few times because i didn't have them and I got my period Feb.9th ended Feb.14th, which was a Saturday. I stayed with my boyfriend Wednesday, Thursday, and Friday and we had unprotected sex everyday. On Saturday I woke up spotting and I didn't feel crampish, on Sunday when I woke up I started to bleed more then usual and feeling sick and not hungry, today Feb.23rd I couldn't sleep last night I was very uncomfortable and felt sick, I woke up and used the restroom and I'm spotting, I eat pancakes and right after i got sick and had diarrhea, i felt nauseated and just layed down on the bathroom floor because it was cold and I'm really hot, I'm getting crampish feeling again and just want to lay down. Can someone help me please?
