Advice please 😫

So I just found out and we don’t want to tell close family until at least our first ultrasound. My dilemma is we have a family dinner every week. We live in wine country and everyone drinks. A glass of wine or a beer or two every time we get together. It’ll be really odd and obvious if I say I can’t drink or don’t want to. What’s a good way to be sneaky about it? Take a glass of wine and pretend to drink it? Idk lol
