Black dots or specks in baby poop

Gl

My LO just had these. She'll be 8 mo this week. Looks like crushed black pepper some are skinny and a little tiny bit longer.

No recent bananas, she's formula fed so it's not because of digesting my blood from nursing like I've read. Not taking probiotics. Just on Gerber Gentle. Any advice as to why this could be happening?

Since she doesn't have a fever or anything serious I can't call her Pedi about it until they open tomorrow.
