C.O.
I never had an IUD but your body needs time.
The pain is NOT normal. So you do need to see your doctor sooner rather than later.
STOP TRYING TO MAKE A BABY!! You are NOT having sex for fun. You are STILL thinking about having and making a baby - your body is going to fight you on this. RELAX!! Have fun!!
I know it's hard. I have been in your shoes trying to conceive ONE...I know what it's like to WANT it SOOO bad. Especially knowing I COULD get pregnant and carry to term!! It was SOOOOO frustrating. But PLEASE - stop.
I truly hope you see your doctor soon for the pain!!
Good luck!!
