"i just had mirena inserted a few days ago. the insertion was not as painful as i had expected, mainly uncomfortable. i had it put in as a reliable contraceptive after my first baby was born. my ob told me numerous times that the mirena is recommended for women who have already had children. i have no complaints about it so far. there was some pretty bad cramping after it was first inserted for maybe 10 minutes. but that&#039;s kind of a given considering something is being placed into your cirvix hole.."
