My doctor never gave me an ultrasound, and said it just fell out. I never noticed it fall out. Could it have moved location in my body and made me fertile?
Mirena - I had an IUD implanted, a year later pregnant, could it have moved and made me fertile?

Did you check the strings regularly to check it was still in place?
The risk of expulsion or displacement is relatively common,(with approximately 1 in 20 women affected).
Most unplanned pregnancies happen to Mirena users when their IUDs slide out without them realizing it. Even though the chance of pregnancy while an IUD is in place is extremely low, if it does happen, you should have the IUD removed as soon as you are aware that you're pregnant.
Women who choose to continue a pregnancy with an IUD in place must have close medical supervision throughout their pregnancy as there is an increased risk of pelvic infection, ectopic pregnancy, miscarriage and early labor and delivery.

Thanks for the info. My strings were cut too short so I wasn't able to check to see if it was still in place ever.
I just want to comment that I am in EXACTLY the same situation. My strings were cut too short to check and my mirena fell out unknowingly. I am 6mth. ppregnant with many 3rd. Reading that this has happened to someone else makes it a bit easier as I really feel people think that perhaps I was stupid not knowing it fell out. My last child was 4.8kg and I have since been told that I probably shouldn't have had a mirena.
