I have read several posts from women having miscarriages after getting pregnant right after removal. It makes sense, because one of the primary actions of mirena is to thin the uterine lining. I would think it might take a couple cycles to get it to its healthiest level. That is just a GUESS however. I would search "pregnant" under this forum-you might get some good insight from old posts. GOOD LUCK! The thought occurred to me too about getting pregnant to rebalance-but I am soooo done with that! lol
