I started a new birth control minastrin to control my horomones cause i get cysts in my vaginal area, armpits and under my breasts and the birth control helps.i started taking aug 16 got alittle acne. I didnt get my period this month i was suppose to get it friday but never came. I had unprotected sex sept 1st but did not ejaculate inside of me and there was not pre cum. Now i have a stinging pin needle feeling in my clitoris whenever i start to pee or touch the clitoris without the foreskin over it. What could i have?
