IUD & Clots

TMI *UPDATE*

I got my IUD placed on Thursday and this started today. I’ve had 3 just like this but a little bigger. It’s not necessarily a blood clot, it’s more like tissue.

* The second picture is what came out just recently. This makes 4 of these same clots coming out. If it was to be a miscarriage would my HCG levels still be detectable on a HPT?
