Miscarriage?

I am around 4-6 weeks pregnant. LMP was 10/31 and ovulation I think was 11/22. Ever since day 1 I have been spotting light brown and light pink. I am on progesterone suppositories.

Yesterday morning I woke up and had nothing but after I went to the bathroom it was a gush of bright red blood that filled the toilet. After that I wiped with a dark red/blackish small clot. However after that I have not had anymore blood, only very light brown spotting. I have no pain or cramps.

Is this an early miscarriage? My dr can’t get me in until next week :/ I just want to prepare myself.

I still have extreme fatigue, nausea, and dark positive tests.
