I'm a 16 year old female. I am on birth control pills, but recently after I masturbate, or during..I get bloody discharges. There was a little a few days ago and I thought it was only period spotting. Then today, there was blood covering my hand during masturbation. Oh, and it started after I was skipping my period with the pills.

My weight is average for my height, but i'm not totally active everyday. I rarely eat meat or poultry. I hope someone could answer my question..why is it that blood comes out during/after I masturbate?
