Measure
6 Hour Foley
The participant will have a cook catheter inserted digitally or by direct visualization with a speculum with the uterine component of the balloon inflated to maximum 60mL. The catheter will be taped to the inner thigh with gentle traction. Participants will be started on hospital-based oxytocin protocol. The cook catheter will then be removed at 6 hours, determined by randomization. At that point health care providers will manage active labor. Foley catheter length: see arm description
12 Hour Foley
