How to Avoid Drinking? *Slight Edit*

So my fiance turns 21 on the 10th, and we planned on having a few drinks with his parents to celebrate. However, I'll be 7 weeks pregnant the day of his birthday and we're not planning on telling anyone until we're well past 12 weeks due to a traumatic missed miscarriage in October. I'm not sure how to hide the fact that I won't be drinking from them. I barely drink to begin with, I usually just have one drink which makes it a little easier, but I just have no idea how to hide it lol. Does anyone have any tips? If it comes down to it, will one drink hurt? I don't even want to

*Edit*

We're drinking at home because of covid and not going out, and there will only be 5 of us total
