I had mine taken out 12/09 and I fell pregnant 6/10. For me it felt like forever but my dr said that it was normal. Everyone is different...some women fall pregnant right away and go on to have a healthy pregnancy and some don't. It's hard to predict how your body is going to react. I wish you the best of luck.
Sakinah69- I'm sorry for your loss. =o(
SSBD to you both!
I would wait for at least 3 cycles. I had it removed in August, fell pregnant September miscarried Oct, fell pregnant at the end of Oct and just now started losing the last one. Merina is a horrendous thing to put in your body. I had A LOT of trouble with it when I had it in, but most of the symptoms I had I didn't connect it to the Mirena until I had it out. I wish you all the luck in the world. (in saying this, everyone is different)
