You should call your doctor to explain to him/her because you shouldn't be having really any labor pains because your only 23weeks and your baby is not fully developed yet,also you should talk to your doctors and tell him/her the pains that your having and also if it gets any worse you need to go to the emergency room right away,you don't want your babys life or your life at hold,but if I were you I would call you doctor and tell him/her whats going on and let him/her check you out,best wishes
