i got pregnant exactly four weeks after my mirena came out. i lost the baby after a month of finding out. i believe deep in my hear that the hormones left over from mirena is the reason why. i would suggest using another form of bc for a couple months before trying. i also know a lady who got pregnant within three months of mirena removal and kept her baby. in my case i think it was too early after it came out for the hormones to have been out of my body. the baby wasnt planned, my husband had even had a vasectomy 10 days before we found out i was pregnant. but we still wanted it. actually, none of our pregnancies were planned. i guess out of 7 pregnancies, two kids aint too bad.
