you never know! i was praying for the same thing when i was pregnant, my back and shoulders were constantly killing me, but it never meant labor for me, but every person is different. your body may just be getting exhausted from lugging the baby around
is it your lower back? if so it may mean labor or it could just be you arer sore from the extra weight.If the pain is high and around shoulders just hang on mommy, it is just the weight.Has anything else happened? like mucus plug or any BH contactions or diareaha(sp? sorry)?those are all signs of early labor, and by early it could be weeks early. If you are not sure call doc. Good luck mom!
