birth control
"VERY irregular periods, I can't remember the last time I was not on it. It has been almost a year. Bad mood swings no sex drive, acne everywhere lots of abnormal discharge headaches lower back pain tired all the time. The arm I got the implant in always hurts whether its cold outside or not. It is always sore, also weight gain, mood swings pretty bad over little things, emotional all the time. I have had nothing but a bad experience. "
