I'm a physical therapist, but I'm no labor expert - but I would doubt it's labor if it is up higher. That area of your back (bra-strap zone) is really one of the points of your back that pays the price during pregnancy (well it all does . It's probably just the change in strain/position on your back because of the baby's size and position. It wouldn't hurt to call your practioner if it continues, but if that is your only symptom, I wouldn't tend to think **labor**.
