Hiya
My first sign of labour was my waters breaking in the evening, i'd had nothing before that!! Although i was absolutely knackered and quite achey all day
I would say that all your niggley pains and aches are your body gearing up for the big day so get plenty of rest and to totally contradict myself try and walk as much as you feel able to aswell. I'm convinced it was all the walking i did that brought on labour for me, i walked loads every day and the day i went into labour (xmas eve) i must have walked about 3 miles through a forest. Like someone else said tho, even tho your body is starting to get ready it could still be a couple of weeks until anything actually happens and its so frustrating just waiting and watching every sign. Drink raspberry leaf tea (or take the capsules) i'v never given birth without but i had a really short 2nd stage with them so i'd say they helped! Good luck and let us know when babys made an appearance
