What should I do with breast milk after drinking?

This is my first time breast feeding and well I had a little drink this morning 🤭 I made sure I pumped before consuming the drink (which was around 10am) and I haven't pumped until now in the evening (7pm) I'm wondering if my milk is good or should I throw it out? I only had one drink in the morning so I'm confused if the alcohol is still in my system and I should throw out the milk? Bc I did pump about like 11 oz :/ ... [side note my baby is also formula fed. I alternate]
