Honestly, you should be okay. 4 days before I find out I was pregnant with my son, I had a little bit of binge to say the least. Most girls don't find out that early and continue to drink. I wouldn't be worried about it
As long as it wasn't a heavy drink, or you didn't drink a lot you said you only had two drinks so I think you and the baby should be ok.
Nothing to worry about as long as u don't continue to drink. Lots of people have had drinks in early pregnancy without knowing with no problems. Good luck.
