Drinking during the tww

I haven't told any of my friends that hubby and I are ttc. I have a girl's night coming up, and we usually chug it down when we have these little get togethers. At that point, I'll be 8DPO. Is it safe to drink during this time? If we actually succeeded, at that point baby would be implanted. I don't want to set off alarm bells by actively avoiding drinking, but it don't want to harm baby, if it exists at that point. Any advice? TIA.
