OKay so my last period was almost three weeks late when I got it it only lasted three and a half days, and pretty light. ABout a week later I got a extreamly little amount of pink discharge I have taken four hpt that have all came back negative, But I haven't stopped cramping sense what I thought was my last period. THe pain is getting almost unbearable.. every once in awhile I'll stand up get dizzy like I stood up to fast but I didn't.. I have also been having to pee alot and almost every time these is a fair amount of clear odorless dischard. BUt the test are making me think something else more serious is wrong I'm starting to stress. I'M also noticing I feel completely empty right after eating what can be wrong??? please help
