Completed · Not applicable
Conditions studied: Pelvic Pain, Headaches, Emotional
In brief
The purpose of this research study is to assess hormone withdrawal symptoms in women while taking an oral contraceptive in the novel 24/4 (24 days of "real" pills) manner in comparison to taking pills in the standard 21/7 (21 "real" pills) manner. It is hypothesized that the 24/4 method will reduce common hormone withdrawal symptoms compared to the standard 21/7 regimen. It is further hypothesized that women using the 24/4 regimen will report greater satisfaction scores.
