Is brown discharge a bad sign?

I’m only 3 DPO so I know it’s not implantation bleeding, but I’ve been getting brown discharge every time I wipe the past 2 days. It’s not a ton, just a tiny spot on the TP when I use the restroom. I’ve never had this before. Can this be a sign of a hormone issue or ovarian problem? I’ve read many women with brown discharge have diminished ovarian reserve or endometriosis. 😐
