birth control
"I got mine placed in August of 2014, I had a normal period after insertion and then the annoying "last day period" nonsense for three weeks. From September to March I had no period! Absolutely wonderful! However, now I'm getting break through bleeding, curiously the day after I have intercourse. It will be very tissue-y and not the typical period-like stuff. It lasts anywhere from a couple of days to over a week. I thought at first that maybe I was just getting a period. But since the beginning of March it has happened 4 times. I called my doc and she is going to get me in for an ultrasound and exam. She doesn't think its normal. Besides that however, I've had no issues."
