TW: blood photo - could someone help me identify this?

[ggllss]

Hi everyone, I’m sorry if this is not the right place to post but I’m really panicking and I need help.

This week I took the abortion pills after finding out I was 4-5 weeks pregnant. On the second day, 2-3 hours after taking the misoprostol I passed this blood tissue/clot(??) which was as big as my thumb. I’ve had some mild bleeding since than but no other clots whatsoever. Is this what I was supposed to pass? Or should I be worried?

It seemed to stay one piece when I put it under water and there is a white circle kinda shape right in the middle of it.

Thank you very much for your help in advance.

Guessing the white circle thing might be the baby and sac, the rest placenta and womb lining? Not medically trained though. I think you'd expect to pass some tissue though. They should have explained what to expect better.
