3 month old conjunctivitis

Nikki

So my daughter is 3 months and 23 days and she’s my first and only child. yesterday I notice me she kept rubbing her eyes and the left one was so watery and kept tearing up. This morning, as she was sleep I noticed yellow green discharge from that left eye. No fever or discomfort just that discharge. I applied warm wash cloth and put some breast milk on it. I’m freaking out. And don’t know what else to do. Should I wait until Monday to get her to see her doctor?any advice would help
