Should I be concerned?

Due date tomorrow, haven't really suffered from PGP / SPD. Woke this morning with sharp pain at front of pelvis like a bruised feeling as if someone has punched/kicked the bone.

Is this likely to be a sign of labour or just pelvic girdle pain? Hurts to walk/sit/get up... My husband has had to help me to go from sitting to laying down by lifting my legs etc.
