Just pregnant with girls weekend coming up

Hello,

I just found out I am pregnant (1 week post ovulation). I have a girls weekend away this coming weekend, we all have kids so this has been planned 6+ months in advance. Thoughts on how to get around not telling people I’m pregnant when they question why I’m not drinking? They’re doing one of the cocktail competitions so I feel it’s going to be super obvious whatever I say 🤦🏼‍♀️ I am close with the host (her birthday) but not the other girls and one that is going I know to be a huge gossiper. I’m so early so don’t really want to have to tell them yet 😣 someone help please. Thanks for reading if you got this far ♥️
