New User of IUD

Kat

So I got my IUD in about a week ago and the cramps haven’t really stopped. They’ve just come and gone. It’s drawing near to my period (it should come in about 2 days) and I have been experiencing extreme amounts of pain. The IUD is tailored for teenagers with no hormones, but I am nervous that my painful cramps will just persist and not get better. Is it normal to be in such pain when you first get an IUD?
