is my iud okay?? should I be worried??

I just got my iud on the 13th of this month. I've had cramping ever since I got it in and I was told it was normal.

but today i have noticed i can barely bend down or lift up my legs to remove my pants with out feeling intense pain in uterus. if I lift my left leg up the pain is on my life side vice versa. I've been bloated as well. I just want to make sure this is all normal and not something I just take to my doctor
