35 weeks pregnant extreme pain in between labia and inner thigh and ox no bumps, no itching, no discolor?

I have this shooting pain in my upper inner thigh, , and around labia on left side, it is so painful, that at times I cannot walk and it only is severely painful when I sit for more than 20 minutes and/or if I sit on a hard surface and try to get up it is so painful, but there is no discolor, no funny discharge, no bumps, bruises, varicose vein lines, nothing different about my body just that it internally hurts. Will it go away, will it stay, what could be the problem, is the baby on a nerve, I know I was driving a stick shift a lot with no power steering and hard to shift could I hurt myself doing that?
