Hi I just login in today. I am 18 years old and I am in college. I have real irregular periods. Sometimes I can go three or four months without a period and ten my doctor will have to give me some medicine to make it come on. But this is my problem: After not having a period for four months i took the medicine so on february 12 my period came on then it went off on the 19. I went to my doctor and he gve me some birth control pills to try and make my period act right but I had a real bad allegic reactions so the emergency room doctor took me off of them. But then on the 26 of february my period came back on and it went off on the 4 of march. me and my bf have never use a condom since we hve started having sex. So around the end of my period we hd sex and he never ever pulls out. We continue to still have sex this even after my period went off. I could i be pregnant? Please right me back or even txt at 662-295-9517 this is really important to me.
