I Had mine inserted 01/2006 and plan to have it removed in a couple of weeks. My husband and I would like to start trying to get pregnant (I've never had kids) soon. My experience so far includes: Sever abdominal pain for the whole first week - I had a heating pad on my lower belly that whole time and had to be drugged up from the "widening" of my cervix.
Afterwards - almost constant cramps all month long, mild to severe, no period blood or very little, mood swings like crazy, pain during sex (dependent on position) and pain after sex so severe sometimes I would cry. I swear I have cysts from it - the ultrasound said so, but they said that could just be from the hormones? That made no sense! The doctor never suggested having it removed though. Great birth control - you have painful sex, so you don't want sex!
I have a great sex drive though and we have found ways around it. I have to take diflucan every week to keep me from getting thrush, never had that problem before. Can't wait ot have it out, however, I'm really worried about the bleeding so many have experienced after its removal.
