Awkard situation

A friend of mine is pregnant with her 2nd child and is talking about how its "okay to drink since she's so early in the first trimester" she's due in May I think so she isn't very far along but it makes me very uncomfortable.

Another mutual friend of ours had her over and she drank a regular size glass of wine.

I can't imagine a doctor would ever say its okay to drink in any stage a pregnancy but idk what to do. I'm not real close with her so I don't want to insult her or hurt her feelings but I'm also worried about her baby

What do I do
