Drinking during ovulation

Soo iv been trying for our second baby for the past 12 months and this weekend I will be ovulating but also I’m going to a 30th birthday party and our 2 year will be at my partners mums house for the night so I am REALLY keen to have a few drinks. What’s everyone’s thoughts will it affect conception or if I would fall pregnant will it affect it that much being so early on?

I don’t usually drink until after my period is finished but this party and ovulating is tied in together this weekend

Thanks 😌
