I'm almost 19 weeks pregnant with my first and I'm having some crazy pain that I can't seem to find in any of my books. Basically, every morning at 6 or 7am, I wake up with intense, cramping pain in my ribs and back. It extends from, say, my oblique muscles in my abs all around to the back, middle ribs. Intensely painful, it is nearly impossible to get a nice, full breath in. I can't really lie still because I'm fairly vibrating with muscle cramped-ness. My voice gets shaky, I'm so tight. So despite the fact that I am forever sleepy and always ready for a nap, I hardly look forward to bed anymore, since I always wake up in pain.
Otherwise, it's been a beautiful, easy pregnancy.
Is this something any of you has experienced?
Edited: this doesn't feel like a digestive issue at all; purely muscular.
