COPPER IUD pains??

Shania

I got my IUD put in almost 9 months ago and I got it checked once after a couple weeks I got it and the nurse said it’s in place.. BUT my period cramps are worse than ever since I got it, and I’m bleeding so heavy I have to wake up in the middle of the night to change my pad!? Is this normal? Does anyone else experience something like this? HELP!!
