Is this me passing my chemical?

I had a chemical at the end of September and never had a period to shed the lining of my uterus. I went on birth control for a month to hopefully conceive right after stopping. I was a week late and everyday (this is day 4) I’ve been passing large clots. These are only a few I’ve been able to take pics of. There have been a LOT more. Is this me passing my chemical or just normal? I usually never have clots.

Edit: I had several positives in September confirmed at drs office I experienced a chemical. All they said was that my period would be later than usual and to expect to pass it on my own.
