Im 30 weeks pregnant.

I went to the bathroom and saw that the discharge on my panty liner was a brown/bloody color. But when I wiped it was a regular yellow/white color so I didn't pay any mind to it. Well I went pee before getting into bed and I felt a gush of discharge. And that happens alot so I didn't freak out. Instead I continued to put a new panty liner on. When I wiped, it was the brown/bloody discharge again. Every thing I see online says bloody show (aka mucus plug) but its simply discharge. Has anyone else experienced this?
