Need help ladies! Af question

Ok, so I started my AF today, or I thought I did. But it’s acting so strange. Super light pink/light brown flow (ew, I know). Nothing strong enough to merit a pad or tampon, but I am confused as to what I should do at this point because it now appears to have stopped altogether.

Was that my period?

Do I even count that as cd 1 so I can do clomid this week?

What is my uterus even? Lol.
