Go see it!
Not only is it hilarious, but there's nothing not to like about any of the characters. I also liked that we got to see so many different scenarios: a couple who had a one-nighter and got pregnant; a couple who was in a relationship and got pregnant; a married couple trying, a married couple adopting, dads. It had it all! You will laugh the entire 90 minutes except for those 3 minutes where you might cry.
I've never been pregnant (so, God, about that guy we talked about coming my way? Where is he?), but I also like how relatable the movie was. It didn't sugar coat anything. Yes, it's a miracle of life, and yes, I want and will always want babies, but there are gross and uncomfortable things going on there. Also, I stand by my word when I say, my husband (wherever he may be, Jesus) might not get a ticket to the delivery room. Might be just me and the doc in a very dark room. I'd be completely serious if I didn't want to have a water birth.
In conclusion, go see What to Expect When You're Expecting. If my shoddy review didn't woo you, four words.
