Ladies, today out of nowhere I can not walk without limping its sooooooo bad it's painful at times.i had my nst and fluid scan today at the hospital and they said the way he's head down is perfect but his back his on my left side. I'll be 38weeks this Wednesday what can I dooooo????? What is this even called? I've never felt this before at all, it's sooo uncomfortable and I'm afraid of laboring like this. Anyone have any tips at all or knowledge on this.
