"I've had my IUD for a little over a year now, and so far I have no serious complaints. The insertion process was very uncomfortable and afterwards I was in the worst pain of my life for about an hour before the ibuprofen kicked in. I honestly had difficulty walking the contractions were so bad. But once the ibuprofen started working I felt completely fine and never experienced any pain after that day. My periods did get a bit heavier, to the point where there are times it's so heavy I think I'm having a miscarriage, but I don't really mind it and it is significantly better than the alternative. I've had several horrific experiences with hormonal birth control before, so this has been a lifesaver and a huge peace of mind."
