So background… I had a chemical pregnancy in December bled for 7 days and ovulated late(unconfirmed. Just tracked with opks)

I just started my period for January last night, and today I had a very large clot. The biggest clot I have had in 10 years. It seemed like it was about the size of a sand dollar.

Does this have something to do with having a chemical last month? Or just happen by chance? I didn’t even have clots this big after having my son.
