Labor is lots of pain. It may be the quiet before the storm

I know a lot of women are exhausted before L&D, and that may happen the day before, or the week before, or even longer.
As for no pain, I bet babies have moved position for you, and this helps to ease some of the pain. Plus, your body may have been stretched enough that now, there's little growth and so the pain of growth and ligaments pulling is no longer too bad... it's already been done!
Hang tight, relax, rest up and just wait and see what these 2 have in mind
