I’ve had a coil in for 2 years and at the start of the first lockdown I had a massive bleed with what appeared to be a foetus in it. I brushed it off as I hadn’t been recently sexually active and thought it could have been decidual cast. I was incredibly stressed at the time due to working, homeschooling and the break down of my relationship so didn’t go to the doctors. I’ve just checked for my coil strings (I only did it a couple of time when I first got it) and they’re not there. Is it possible for me not to have noticed it falling out?
