"first off getting this put in was absolutely horrific. after insertion i had to stay there for an hour of cold sweating before i was halfway able to drive home. the awful cramps lasted for 4 days. i only had two periods in the 7 months i had it. i gained 40lbs while eating better and being more active, got awful body acne, lost hair, and have had bad constant headaches, which i have never had. on the bright side removed is completely painless, i switched to paraguard."
