Will anyone be celebrating their birthday while pregnant?

I'm the kind of person that comes home after work and likes a beer or a cocktail with dinner. I was a social drinker whenever we had a party or get together. (Which is why I had to tell everyone early because I couldn't turn down a drink without making everyone suspicious) My whole family likes to drink so now that I'm pregnant I'm dreading going to a family party and being the only sober one. Is anyone else struggling with this? I don't want to be one of those annoying pregnant women who doesn't let their spouse drink and hates to go out. I still want to have the same fun personality I always had at parties but it really sucks being the only one sober with a bunch of drunk people. With that being said. What are some ways to celebrate your birthday without alcohol?
