Still pregnant

Now I'm overdue, which is fine by me, but I start to worry the more days go by as overdue babies start to develop health concerns as conditions inside their warm little home start to deteriorate. I have started poking at her regularly to make sure she's still moving around: a very quiet, still little one! If anything, I look slightly smaller now, tighter, as it's like there's less fluid in there now.
I had myself resting a lot the past 2 weeks, but now I'm up and around more, working out, cleaning, walking. My feet are killing me! I've never been one to believe one can affect starting labor, but bed rest must be effective if so many women have to do that to prevent pre-term labor! The opposite must also hold true, right?
It makes me so sad, trying to get her to come out. Reluctantly trying.
