So, recently I have just started to get a weird feeling. I had PROTECTED sex with my boyfriend on the night/morning 19/20 of this month(January). I got my period the morning after we had sex.(20) It was a regular period. Early a little bit though. And heavier! Normally my period last around 3 days, with the 4th day the ending bits. But this time is was around 6 days. So I didn't think anything of it. I had a slight cold before we had sex and I still have it( sore throat stuffy nose) and I ALWAYS have a headache. Im laying down right now and I have a light headed feeling. I feel a weird feeling in my lower stomachs. Kinda upset like needing to vomit. But no vomiting. And today I have.VERY loose stool.I thought maybe I ate something. But feeling nauseous for a couple days randomly got me into thinking maybe I was. I'm not peeing anymore then normal. I'm exercising( loosing weight/gaining muscle I think from working out 3 times a week). So what do u think? If u need more info just comment and ill respond. NO breast tenderness either. Thanks
