Wtf is happening?!

My period is usually dark with some bright red blood (more dark then red) on day 5 and it’s usually wet like. But now, I’m on day 5 and my blood is bright red and it’s dry like but not brown. I know I’ve been stressed out lately. On day 4, my flow is heavy but this month, it was lighter than usual. Wtf is going on??? It’s stressing me out even more!
