I have had my period for about 8 days now. It has been alot lighter than usual. I was even able to wear white while being on my period which is very unusual. I can barely hold any food down. I feel sick all the time. MY brest and stomach got bigger. I have to pee every 10 mins it seems, but I dont drink that much. I wake up feeling like I am hungry and thirsty. I thought I might be pregnant so I took two at home pregnancy test and they said negative. So what is wrong with me?
