Pregnancy ?

Hey guys so in the first couple of days of September I miscarried

The first week of October I had a heavy period (every period I have is heavy for at least 3 days)

This month I experienced spotting for about 4 days it was light pink and brown

Then a week later I had a period (this period was light, I didn’t even clot like I usually do. A pad could last me the whole day with this period but the blood was actually red)

Do you know what might explain this ?

Do you think pregnancy could be a possibility?
