Help I'm concerned

Michaela • 22!! future educator 💚🙋📖
I've been spotting brown discharge for 2 weeks. The last couple days have been large chunks of tissue. It started two days before my ovulation was ending. I'm now supposed to be on my period but I'm getting globs of this nasty brown discharge. I'm 20 and not sexually active.. should I see a doctor I'm also not in any pain... or smells that I've noticed.
