High alcohol tolerance

Did anyone else experience a high alcohol tolerance before finding out they were pregnant? With my first pregnancy I took a test and it was negative so I drank at a Christmas party and didn’t feel a thing and normally I’m a light weight. Found out I was pregnant a few days later. Fast forward a couple years and two back to back babies and never drinking, I went to a Christmas party and had four drinks quickly and I was drunk for maybe 2 minutes then it was like boom sober again! Anyone else?? Kinda freaking out that I might be pregnant again🤦🏼‍♀️
