I stopped taking the birth control pill Errin about 2 1/2 months ago because I was gaining weight and couldn't get it off. My husband and I have not been using protection of any kind. About two weeks ago I woke up extremely tired and this has continued almost everyday. A few days later my stomach started to be upset several times a day. After that came the headaches. They were bad and would continue for about an hour even after I took something. (Tylenol because I have a child already and still have it from when I couldn't take aspiren with her.) A couple of days ago my temperature when up about a degree and has not gone down. I have taken a home pregnancy test early last week but it was negative. I also have been experiencing unexplainable mood swings. I almost cried several times this week when everything was completely normal and I can not express how odd it is for me to even think of crying let alone actually do it! Anyway I want to ask. How likely is it that I am pregnant? Or am I more likely to be sick even though this has been going on for weeks?
