what's wrong with meeeee

Jules
My mom took me off the pill for several months bc she read that it could cause cancer etc. but then I had to go to the er bc I had a ruptured ovarian cyst in my left ovary and and couple little ovarian cysts in my right ovary So my gyno started me back on the pill I was on and I started having really bad chest pain and nausea and it just didn't feel right at all so I just stopped taking it knowing that I'm going back to see my doctor this month. But today I started my period 2 weeks early and normally they're never early or late it's always right on time. And it doesn't look like blood normally at the end of my period it's like a reddish brown but today it looks almost black! I don't know what going on please help
