birth control
"My experience has been mirrored by another recent poster; I got mine I  mid-November 2014. I had two very light periods and then mid-January 2015, I started a period that hasn't stopped for more than 18 hours. I've been spotting for more than three months straight! 

I can still work out, I drink plenty of water and eat good food, and the cramps have only been bad once or twice (after a nap I was ok). I think staying hydrated and eating a diet rich in protein will help some of the symptoms others experience. I've lost about 15 lbs (neither hindered or helped by the device), been a little moody and had a very mild increase in acne."
