D.P.
I still have my Mirena IUD in, but I remember being told by my OB that once it gets taken out it could take a month or two to get my body back in sync. I don't get my period anymore, I'm not sure if you did while on the IUD, but it will take a cycle or two to renew your uterine lining and such. I do know that Mirena claims a high successful pregnancy rate 6 months after removal :) So that is hopeful. Goodluck!
