This is going to be a long post, but someone please give me some advice.

Ok, so I had my daughter Feb 5th of this year, I bled normally after my c-section and had one period between then and may 17th when I got the depo shot. I had not bled since then until the 9th of this month and in all actuality it wasn't blood at all, it was brown and boogery, that lasted until the 12th. Then today I woke up and thought I had started a real period because it was fresh red blood like usual, but now it is brown and nasty again. My grandmother died at a very young age from either cervical or ovarian cancer, I qk not sure which but regardless, this is worrysome. I went to my gyno and she basically said its normal, I explained to her that I have all the symptoms of pcos (extreme facial hair, excessive weight gain, hair loss on the head, cramps so severe it is like contractions, no periods, and headaches) and she checked NY hormone levels and since they were normal she said there's no way, well clearly something is messed up, should I demand a pap and further testing or what I am officially out of ideas. I have gained over 50 lbs since my pre baby weight, 285 lbs is not a good look. I have dieted, worked out, nothing is helping.
