So Ive been dating my boyfriend for awhile now and we have sex numerous times, so this past month i decided to get the "nuva ring" and we haven't used protection since Ive been on it. I ended up getting a bladder infection like 3 weeks ago and the doctor said it was pretty bad so she gave me antibiotics for it, but now when i have sex with my boyfriend after 30-45 min it hurts so bad i just stop and when i pee after sex it burns so bad i want to throw up, but then the pain goes away after 20 mins. I have been tested i have no STD's and neither does he. Is the only reason why i burn and it hurts cause i have a bladder infection.. or could it be something else?
