Contaminated Breast Milk

My baby is 7 weeks old, I needed a drink so I had a semi heavy drinking night with bf. Stopped drinking a little before 4am. I pumped that same night because I was full, and I dumped that milk. I pumped again the next morning, ended up testing that milk with Milkscreen and I THINK the strip turned A TINY BIT of brown so I dumped that milk too just to be sure. When I thought I was in the clear, I pumped again. Tested that milk and to me, it didn’t look like it changed a color. And today I used that pumped milk, now I feel like my baby is sleeping ALLL DAYYY LONNNGGG. I’m freaking out and being paranoid that maybe my milk still had alcohol in it. Anyone think something could be wrong with my baby? She seems pretty normal, she’s smiling, eating, peeing/pooping, just sleeping a TON. Any help would be appreciated.
