water broke- at hospital but barely any contractions! Help! We get to walk every 20 minutes, otherwise on monitor. Ideas needed!

Mags • Baby #2 due Sept 2016!
Water broke at 12:30.  Need ideas to get labor moving, we are already walking the halls when allowed (40 minutes off of monitors, 20 minutes required to be on). Help! We have to get this labor going, since I am attempting VBAC.  If things don't progress within the next 5-7 hours they are scheduling the c-section for tomorrow morning.
