39 Weeks Pregnant and I'm 30!

So today is my 30th birthday and I'm 39 weeks 1 day pregnant. I was quietly hoping she would be here before my birthday but deep down I know I'll most likely go overdue. I'm really getting uncomfortable now but I think that has more to do with my physically demanding job. Unfortunately not working is not an option for me but I think I'd go crazy sitting around at home anyways. My doc has been having me do weekly NST and BPP's so that keeps me somewhat satisfied.
