Mirena iud
I had the mirena and that is why I am currently 16 wks pregnant. Just about 1 year after I had it put in, it came out. I went to the bathroom one day and went to do my string check and they were right there not inside like they should have been. I pulled it out. Had no pain or bleeding, until I started my period for the 1st time the next day. I have read a lot about it after that and apparently its a pretty common thing. Good Luck!
It is possible for IUD's to fall out. That said, the only way for your doctor to FEEL it is by feeling for the strings. The strings can retract, mine did with my first Mirena. The only problem it causes is that you may have to have sedation to have it removed because they will have to use an instrument to reach in and grab it.
