I have had the Mirena IUD in for almost 5 years and had already decided I would get another when the time came. However, I "felt" pregnant for the last week or so... pregnancy test was positive. I, too, am in my 40's and was shocked and devastated to find I was with child. I chose the Mirena because we were done building our family (4 kiddos) and I have health issues that needed tending to. After the shock of finding out I was pregnant, my mothering instincts kicked in and I began a furious search for information and providers to help me make the decisions that would best benefit the health of my baby. The Mirena was removed post-haste but the waiting game began. I was told I had a 50% chance of miscarrying due to the IUD being removed, but it was safer than leaving it in at this time. I was told yesterday that my HCG levels are dropping. I cannot express the anguish I feel. It may not have been planned, but it was already loved. Never, ever, have I felt so helpless, so empty.
