Hi M., I had the Mirena IUD between my 2nd and 3rd for 3 years and i had it taken out in March of 2005 and I was pregnant by June of 2005. I have to say that I loved it and I am planning to get it "installed" again after I have this baby I'm prego with (I didn't have it between baby 3 and this one and hence....) It's a great IUD with little or no side effects as far as I could tell. Good luck!
