Brown discharge !

Very recently I had my period from 30th of July until Aug 4, it’s was a light period too. I’ve been paranoid lately because of the brown discharge that started Aug 9,it went from light brown to dark brown(I also told my boyfriend about it too.)Today I went to the bathroom when I wiped it was dark brown mixed with red like period blood. Idk if I’m ovulating or something is going on ? But I plan to go to my doctor tomorrow.

Any thoughts on this?
