Veronicaco, I've had an increase in cm for two weeks before birth in all my pregnancies so far, so you may not have too much longer left to go! As for feeling like you're effacing, that reminded me about the night I went into labor. I was sitting on the couch wondering whether or not to go to the hospital, and during my contractions, I could actually feel my uterus pulling upward all the way down to my cervix, so I was actually feeling myself dilate! It was pretty weird!
TTC, I'm not sure if you remember, but I had a crampy back for a few days when I was about as far along as your are now, and I did end up calling my OB, because like you, I was concerned about PTL. Their main concern was whether the back pains were coming in timeable intervals. When I said no, it's kind of just a steady pain, they said than it was most likely baby's position, and that I could try getting on hands and knees and rocking to shift him.
M2C, I'm sure your bloods will come back fine. That's unfortunate that you have to wait a few more days to find out, though!
Cangaroo, sorry your DD is poorly.
I do like your name choice, though. And that's good that your DH admitted he didn't really like Ruby, rather than going ahead with it and having regrets later.
VJean, not much longer left for you!
Zephyr, I'm feeling sore today, too.
I think I felt better yesterday, and so I definitely over did it with the kids, and am now suffering for it.
