if your at all worried go and get yourself checked out, it maybe a simple case of an upset tummy, but it maynot, its much better to be on the safe side and if everything is ok, thats the best outcome, if not the hospital may be able to stop it if its pre-term labour
Sounds more like a tummy upset to me. In labour your tummy would be visibly tightening and that would be the only time it would be painful to touch. My kids were very still during labour too. Make sure you keep up your fluids and it would without a doubt be worth going to get checked out, but I dont think it's labour.
