It sometimes takes a couple days for it to work. Just do lots of walking and more walking! Take a hot shower or bath also and just relax.
Im right there with you,I had one done last week and one yesterday,it will be the last one i get,i think it worked thoe because i have been cramping all night,sometimes if youre not dialated enough it doesnt work as well..ask your dr for a second one see if it works,good luck to you..
