When I last got my period I had it for 6 weeks, I went to the doctors an he made me take a pregnancy test and it came back negative he was a fill in so he didn't really give me an answer he gave me some cream too insert into my vagina it took 3 days and my period had stopped. I now have my period and I'm in the second week. Its very heavy and has a lot of blood clots :/ I leak right through a tampon and a pad... My stomach also so gets pretty bad cramps time to time... Please help...
