most likely you are just experiencing one form of pain associated with the end of pregnancy, things become more uncomfortable and painful. with my daughter i had my hopes up for two weeks before because of all these pains. one time it turned out being a bladder infection. i ended up going into labor three days late! You will feel the difference because the labor pains start out as a dull period cramp that continues to get worse. it took me a few hours laying in bed cramping to realize it was really happening.
Even if ub have signs of labor there is no telling when youll go into labor. Ive been having signs since 36 weeks...im 39 weeks now. Ive done everything natural like walking excercises squats sex lol nothing so I jus stopped getting my hopes up and im jus waiting! Goodluck
