Baby has diarrhea that won’t go away

My daughter is 7 months old. The whole family had a crazy cold for a week long. all of the kids got diarrhea and it was only like 24 hours of it. But my 7 month old still has like mucusy diarrhea. Every time she has a bottle it’s like this. She’s been on the same plain infant formula since she was a newborn and never had this issue. I tried calling the doctor to get her in but they’re busy and can’t see her for a few days. She’s still eating, and sleeping. She doesn’t seem dehydrated I just don’t know if this is normal.

I’m wondering if it’s maybe from her drooling? Or sealing all the mucus all week she was sick?
