Value of Mifepristone in Cervical Preparation Prior to Dilation and Evacuation 19-24 Weeks

A common practice for preparation for surgical abortion after 19 weeks gestation is the
placement of multiple sets of osmostic dilators 1-2 days prior to the procedure. The
investigators aim to study the addition of mifepristone as an adjunct to cervical dilation
prior to abortion between 19-24 weeks gestation, and its potential to minimize the number of
painful procedures and time in clinic (or away from work/home) that multiple sets of dilators
can require. The investigators hypothesize that one set of dilators with mifepristone will
result in similar procedure times and decreased "total" time as two sets of dilators.
