Might’ve had a miscarriage?

My husband and I are ttc for 3 months so far. I have Hashimotos/Hypothyroidism.

Anyway, I had a period this month but I had a Blood Clot on my toilet paper when I wiped and I’ve never experienced this before (clots). Also, my period was 2 days longer than it normally lasts.

Is there any way that I can find out if I had a miscarriage? My period ended yesterday.
