Medication and alcohol when TTC

Just curious on people’s thoughts about having things you wouldn’t when you’re pregnant in the TTC phase. I ovulated about a week ago so still about a week to see if I get a period or am luckily pregnant this time. I am not a big drinker but have a party on the weekend and so torn whether to have a couple of drinks or not. Obviously as soon as I knew I was pregnant I would happily give up all the risky things but in the meantime it feels like putting life on hold when maybe this isn’t the month. I had a similar mental debate a few weeks ago with cold and flu tablets so just very curious about others views.
