abnormal uterine bleeding
"I thought I'd throw a positive review out there. I've read so many negative ones. I'm 19 years old. I've never had children, so getting it put in wasn't very pleasant, but not terrible. I got the Mirena because I was bleeding for almost a year straight, very heavily. The only negative side-effects I've had so far are bloating, cramps, and moodiness, but they went away after a week or so. I've had no weight gain whatsoever. I've actually lost a few pounds...Yay! My sex drive has actually gone nuts (in a good way), and my periods have stopped! That's the main thing I'm happy about. I was tired of bleeding all the time. I'd recommend the Mirena to anyone."
