I wanted to share my story, and see how many other women are going through what I am; I just found out 2 days ago, that I am pregnant with my fourth child, while on the Mirena IUD! This was quite a shock to me, since I have had the Mirena for almost 5 years, and a day before I had the pregnancy test, had received a call from my dr. to set up the removal and replacement of it for Feb 2012. At my last annual exam, I had discussed the option of tubiligation versus IUD, and was convinced that Mirena has the SAME effectiveness as a Tubal, so I decided to stick with the Mirena. Since finding out I am pregnant, I have done a lot of research, and had a lot of testing done, which I am still in the process of...once I got the positive urine test, had to make an emergency appt with my doctor to see where my IUD was..to my surprise, it was EXACTLY where is was supposed to be! so a blood test was done to check my hcg level and to confirm the urine test. before removing the IUD, my doctor wanted a stat ultrasound to rule out ectopic pregnancy, which can occur if you get pregnant with Mirena. Unfortunately the U/S didn't show anything except a cyst on my left ovary, which is due to the fact that my hcg level wasn't high enough, and I wasn't far enough along to see ANYTHING, so I left the doctors more confused and with no answers to how, why, and still in utter shock! Due to the High Risk of this pregnancy being either ectopic, misscarrying, the reccomendation is to have the IUD out ASAP. So, I had the IUD removed, but because I caught this pregnancy so early (at 4 wks and 4 days!) I have to go for repeat bloodwork today to see if my hcg levels are doubling like they should in a normal pregnancy..if so, my chances are good that the pregnancy is in my utuerus where is should be, and hopefully we got the IUD out in time. If my levels are low, that is a good indication that I am either carrying an ectopic pregnancy, or will be miscarrying...I'm curious to hear what others have gone through. Have you had a confirmed pregnancy? how did you handle it? what was the outcome? I'm glad to be able to share my story!
