I have been having really bad stomach problems for the past couple weeks.It seems to get hard in some places, and my sides begin to hurt. It's been hard to try and eat things and keep them down. Last month I had my period but I spotted for about a week, then after I stop spotting I had a constant flow for about 2 1/2 days, then stopped. I don't know if I am pregnant or not and can't go out to get a test. So is there a possiblity I am several weeks pregnant. I am also having these feelings about how I am tired a lot more than usual, thought I'd add that.
