I had Mirena in for the full blown 5 years and I ended up getting pregnant a month and a half later after removal but I miscarried. Then around 2 and a half months after the miscarriage(4 months after removal) I got pregnant a second time and now I am going to have a healthy baby boy in the beginning of March. :)I suggest taking it out in January since sometimes it can take up to a couple of months for her to get her period back and should have 2 full periods before getting pregnant to lessen the chance of miscarriage. I know times will all vary between each woman but it's the safest bet if she is wanting to get pregnant around that time.
