The purpose of this randomized trial is to compare same-day cervical preparation using Dilapan-S™ plus buccal misoprostol to overnight cervical preparation using Dilapan-S™ before D\&E at 16.0 to 20.0 weeks. Primary objective: To compare D\&E operative time. We hypothesize that same-day Dilapan-S™ plus buccal misoprostol is non-inferior to overnight Dilapan-S™ with respect to operative time. Secondary objectives: To compare treatment groups for the following: Pre-operative cervical dilation; need for mechanical dilation and ease of dilation if required; ability to complete D\&E without further cervical preparation; ease of D\&E; complications; pain; side effects; patient and provider satisfaction.
