I'm not totally sure if im pregnant or not. I think I ovulated on July 30 and my boyfriend and I had sex July 26 and August 1,2, and 4. I had started getting nausea on August 5 and it continues and got worse until the 8. I was very bloated, cramping, belching constantly (especially every time I ate), headaches, when I are my stomach felt worse. I had elevated temps from August 5-7. My period is supposed to start August 13. I went from being consripated to having diarrea the next. I took I pregnancy test on Aug 8 and 9 and it was both neg. I figured it just might be to early to test yet. But then all my symptoms kinda decreased. My stomach still cramps, and is bloated, I'm still belching. I'm still constipated and have diarreah (it goes back and forth). Then my boyfriend and I had sex and during sex when he pushed in hard it hurt and then after my stomach felt kinda weird. Not like it usually does. It felt really bloated and my back was cramping. I'm not sure what's going on. I'm not sure if im pregnant, or I had the flu or what. Any opinions?
