- Length of Procedure [ Time Frame: Subjects will be followed from the administration of mifepristone/misoprostol or laminaria, until the end of their procedure, a total of two days. ]Interval from speculum insertion to speculum removal
- Operative Time [ Time Frame: Subjects will be followed from the administration of mifepristone/misoprostol, or laminaria, until the end of their procedure, a total of two days. ]Interval from initiation of vacuum aspiration to speculum removal
- Subject Discomfort Before the Abortion [ Time Frame: Subjects will be followed from the administration of mifepristone/misoprostol, or laminaria, until the end of their procedure, a total of two days. ]Pain was subjectively described by the subjects as : None, Mild, Moderate, Severe

- Cervical Dilation Achieved [ Time Frame: At time of abortion ]Cervical dilation at start of procedure
- Acceptability to Patient [ Time Frame: After procedure completion ]Patient was asked whether they would choose to be in the same group again if they had a similar procedure again. The number of participants whose response was "yes" is being reported.
