I have been nauseous, having diaria, no fevers, stomach is really picky on food, I feel like vommiting when I cook food, or if someone cooks it for me, I get extreme heart or stomach acid attacks when I wake up. I took 4 pregnancy tests for this whole month. I am on birth control, and my boyfriend and I haven't had sex since December. 1 pregnancy test each week for the month. Nothing. All negative. Is it allergies? Or a virus. I don't know....
