My period has been on since November 2008. I went to the clinic and they told me it was because I gained too much in a little period of time. i'm doing everything that I can to lose weight, but I just can't. I'm tired all the time and stomach is hard like a rock. When I went to the college clinic, the nurse noticed that my stomach was hard as well. I took a pregnancy test and it was negative. It's like the nurses can't help me, they just tell me to lose weight. Why has my period lasted for a year? Can you please help me.
