Hello. I am 19 years old, I am 196 pounds, and I am 5foot tall.. when I was 8 years old I started my period, and shortly after that I was diagnosed with PCOS. I have never had a regular period. but the last time I had my period, it lasted up until about a week ago (December 2015 to March 2016). I m not 100% sure that it was my period though, I was bleeding, but I didn t have cramps or anything. But now I am spotting and I am having really bad cramps. Why did I bleed for so long? And why am I spotting now? What should I do?
