Bent Implant?

Has anyone had any experience with ending up pregnant while having the Implant? Or any experience with it breaking/bending?

I’ve had the implant in for 9 months now and I’ve not long finished an 18 day period (my periods have been insanely hectic ever since I got it put in), so I know I’m not pregnant, but I went to feel my implant a few days ago and it has a dip in the middle, like it’s been bent in half? It’s still in the same place so it hasn’t moved anywhere.

Has anyone experienced either of these things?

Note: I have a doctors app in 3 days and my partner and I are currently taking extra measures just to be safe.
