hi, I am 40 + 6 today with my third baby and all night have had a persistant, v umcomforable pain in lower back, like someone is pulling a belt tightly aroud, hurts to walk...had a few contrax last night too, but been having them on and off all week...also i keep shivering/trembling...all weird, my other 2 were on time and my waters broke first so all quite obvious...eveything including position of baby is fine at check a few days ago...just wondering if anyone experienced constant back pain b4 going into labour and the shivering thing...promised kids we would take them to zoo today, is this wise?! am having a sweep on tues if all else fails...
