SKYLA IUD!!!

Sooooo... I was had a IUD inserted this passed Monday after 4 years of not being on any birth control... and idk of suppose to be having REALLY bad cramping after a week being inserted but the cramps are so sore to the point where it feels like I’m in labor kind of cramps and I checked yesterday to see if I could feel the strings and I couldn’t feel it. I called my OB that was on call last night and she said it’s nothing to worry about. Mind you, I’ve been having these cramps for 4 days now.. what y’all think?
