Alcohol still in breast milk?

So last night I had a ladies night and got pretty drunk. Baby drank pre pumped breast milk. But today around 12:00 I fed baby and she was very sleepy after and now I’m paranoid that maybe there was still alcohol in my milk? i got home last night around 10:00 pm and was very drunk and fed her today at 12pm. I feel so terrible but my boyfriend says she’s fine and the alcohol would already be out of my milk by then. What do you guys think? I’m scared to feed her. I tried buying alcohol test strips but both Walmart and Walgreens didn’t have them. I might just supplement and feed her formula for today bc I’m paranoid
