To drink or not to drink?

Aimee • TTC #1 since Dec 2013
Im 5 days post <a href="https://glowing.com/glow-fertility-program">IUI</a> and it's NYE. I want to enjoy it with alcohol but scared I'll blame the alcohol on not getting pregnant this cycle if it fails. What would you guys do? I'm thinking I'm not pregnant yet since it's 5 days post, but I don't want to hinder things either. I'm thinking of going lightly, nothing crazy like blacking out or puking. But a couple cocktails should be fine, right? Ugh, I'm torn...
