Pregnant with Mirena?


Dear Midwife,
I have a quick question. Is it possible to get pregnant while having the IUD Mirena?

Mine has slipped and isn't in the proper location but the doctor said not to worry. That was about 2 months ago.

Since December I have gained at least 20 lbs, I'm tired all the time, my breast are huge, and I seem to crave different things then I have in the past. I took a pregnancy test the other day but it was negative. And I don't get a period anymore really. The last one I had was in August. So I'm not really sure what to think. Any thoughts?


If the pregnancy test is negative (and it was a good one), then you are not pregnant. It is possible but extremely unlikely (like less than getting sterilized) that you would get pregnant on Mirena, but nothing is perfect, which is why you do the test. On the other hand, gaining weight that fast is not normal, even if you are pregnant. I think a check-up is in order to find out what is going on.
