Going to the bar while pregnant...

Okay, so I'm in my first trimester (still not showing) and my husbands friend is having his birthday party at a bar with a bunch of friends and I don't want to miss out on a celebration just because I'm pregnant. I obviously won't be drinking but I plan to sip on some really good VIRGIN Strawberry Daiquiris. People know I'm pregnant but I don't want them looking at me like I'm irresponsible since not everyone will know that there's no alcohol in my drink...
