I'm going to go against the grain and say if you are TTC and not actually pregnant, I would relax, enjoy a few drinks and not worry. I'm not sure about alcohol and fertility but in my experience and those of many of my friends, lots of bubs have been conceived when tipsy!! I'm not saying go get drunk everyday, but certainly enjoy your night out without thinking it's going to ruin your chances - in fact, it might even do the opposite IMO.
