when's my turn?

So I'm really starting to get anxious for this baby to come. It seems like everyone around me is having their babies early, and I haven't even had the slightest hint of labor. I still have 3 weeks to go, but really it could happen any time. One lady at work was due Nov. 4th, and she had hers last week already. Another co-worker, her daughter just had her baby, and she was due the day after me. Then at birth class last night, one of the couples was missing because they had theirs on Monday. Jeesh! So when is it gonna be my turn?
