Quoting Sophia'sMumma.7.10.2012:" Sorry i don't know if thats the right spelling or not. I got the minera iud two days ago im having horrible ... [snip!] ... wondering has any fell pregnant using it? What were your experience with it? Sorry for spelling and grammar im using my phone."
personally, i love my mirena. i have had it for about 5 weeks now, and my body is now getting used to it. yes there was cramping for a couple days, and my period has been messed up, but your body has to get used to the type of birth control it is (as your body has to with all BC's)
if the pain doesnt stop within a week or two, call your doctor.
but anyway, GOOD LUCK
