Is it ok to drink while TTC?

I’m trying to be 100% healthy since I started ttc but idk I get stressed out by life and I need a stress reliever. But I’m trying to stay away from alcohol to hopefully help my odds when conceiving but I see multiple people on here either smoking weed/and or drinking prior to finding out they’re pregnant.

So idk I’m on month 3 of TTC but I just want to give in to temptation despite knowing some people still get pregnant while doing those things. 😭
