hi there,
I know exactly how you feel i am due in 7days and i have the exact same problem what i do is try to have a long hot soak in a hot bath and when you hop out your body will be sooo thankful....
But beware sometimes hoping in and out can be a really difficult thing so make such you have you hubby there or someone to especially help you out of the bath or you may do damage or get yourself stuck in the bath...lol
