After about 6 weeks I had to have it pulled out because I could always feel it. I hope for your sake your experience is different than mine. I would never consider it again.
This is really unusual - OP, make sure that your provider has experience inserting IUDs.
I felt something similar to a mild labor contraction for a couple seconds, and then some mild menstrual-like cramps after that. I took a dose of motrin and was fine. I am on my second IUD and won't go back to any other form of birth control (until DH gets snipped...)
