Hi, it has been about a month since my period ended and during that time my boyfriend and I have had unprotected sex. However I just took a pregnancy test today and it showed negative. Over a week ago I was feeling normal symptoms that I associate with my period coming; backache, breast were hurting (and the grew a bit), mood swings, and bloating, but I still have not gotten my period. I'm just wondering if I am pregnant or if it is normal for there to be a break sometimes between those symptoms and actually getting my period.
