How do I hide that I’m not drinking alcohol at a party?

My best friends birthday is on Saturday and she’s throwing a party. The theme is “disco cowgirl” and everyone is talking about how much they’re going to drink and party, and these girls seriously know how to party. I’m talking shots and shotgunning white claws. I’m even in charge of bringing one of 5 different cocktails. I haven’t told anyone other than my partner that I’m pregnant just because I’ve had so many miscarriages. How do I navigate not drinking at this party without raising suspicions? I feel like I should tell my friend, maybe we can hide nonalcoholic drinks for me and I can pretend? What would you do?
