Red/brown Discharge 😧

Bejulep
I think my hormones are unbalanced. A couple days ago my discharge was brown, now it is red/dark red. According to this app, I should be getting my period in 6 days. 
Never experienced red discharge before my period. I don't think I'm pregnant because I got my period last month nor have I had intercourse this month. 
Should I be worried? 
Thank you! ❤️
