brown discharge on tricera lo

Sonjia

Been on this pill for the third month now. I’ve had brown discharge, sometimes that same syrupy stringy texture as period blood, i saw a BIT of red but otherwise it’s still brown and i’m wondering if this is just my period? Can my period just be this gross brown stuff with barely any bright red blood? I’m just annoyed and grossed out by this.

I know it’s old blood but i never really understood what that meant. If anyone can give some insight, it would be greatly appreciated!!
