Hi hun, sorry only just saw you'd replied. I had some extremely painful cramping after insertion, like afterpains for those of you who've had them, and early labour pains for those of you who haven't. I also had some spotting and generally feeling a bit rubbish. My first AF was four days early, and very very heavy, and lasted a week (rather than my normal four to five days). It was also extremely painful. However, Ibuprofen taken regularly deals with the pain and reduces the bleeding (I was bleeding like I'd just given birth for about three days) a lot and now I actually feel fine. I had a few problems with nausea and faintness, but I think that was the excessive bleeding and cramps. I'm told that the second AF is a lot better and that with time I won't really notice any difference, so I'm going to keep it in if I possibly can.
