Active/Very busy mammas?

So everyone always says the more active you are the more likely you are to have your baby a few weeks early etc. Let me tell you I have not sat down in weeks! We moved into our new house and haven't stopped, I work cleaning houses and taking care of life's business! If I have not had this baby early yet I do not think I will! Mind you I feel great still and wouldn't be so nutty if I felt like it was the wrong thing to do or if I was way over tired. So thankful for energy but praying he stays in for the last few weeks !
