Alcohol before taking a pregnancy test

Allison
I was wondering what everyone's opinion was on drinking alcohol before it's time to take a pregnancy test, and not knowing if you're actually pregnant or not?
The reason I ask is that I'm currently in my fertile window, and I have a pool party to go to next weekend for the Fourth of July, and normally would be drinking, but I'm concerned it might be a bad idea if I did in fact conceive this month. 
To some, that may sound a little paranoid, but I'm a worrier and don't want to do anything to jeopardize my chances!
Just curious to see how you guys feel about that issue? Thanks! :)
