IUD fell out

Corrina
So Iv had my IUD for 2 years now sense my 2nd son was born I got it right after my 6 week check up. It's never gave me any problems a couple weeks ago I go use the bathroom as I wipe I feel something stringy touch my hand so I used my phone camera to see what it was and it was my IUD! It just fell out of no where I was freaking out and didn't know what to do and now I'm not on any birth control because I don't have and insurance or Medicaid. Had anyone else had this problem with there IUD FALLING OUT?
