"i had my iud put in about 2 hours ago, so this is going to be based off that experience. also i&#039;m 20 and never had a child. i hadn&#039;t gotten my period yet, and i was worried that this would make the pain worse, but it didn&#039;t at all! the only part that bothered me was the clamp on my cervix, that pinched at first and then just felt like a mild cramp. i didn&#039;t even realize he was measuring my uterus until the dr. asked if it hurt. then he actually put the iud in and again i barely felt it. i felt better once the clamp was taken off but slowly started to get cramps. now i&#039;m home laying in bed with a heating pad with some cramps. everyone is different but to anyone thinking of getting one don&#039;t be scared of the pain, because i didn&#039;t feel any!"
