I'm 36 weeks on Tuesday. I have been walking quite a bit today but the pressure has really hurt me and my thighs are killing like a done a work out which I know is normal but my stomach has been rock solid and getting period pains. They are constant though so can't time them. It's been like this for last couple of hours. Could this be a sign of labour or is it because I have been walking? O also feel twitches in my pubic area. Please reply
