Detaljeret beskrivelse

Period pills (a combination of mifepristone and misoprostol) for people who suspect, but have not confirmed pregnancy, has the potential to fulfill this growing need. In the United States (U.S.), a handful of providers currently offer period pills alongside other contraceptive and abortion services in their practice (https://www.periodpills.org/providers). This proposed study would aim to assess the acceptability of this growing service as a fertility regulation method to be utilized before a person confirms they are pregnant.

Dr. Ushma Upadhyay (Professor) and Dr. Tania Serna (Associate Clinical Professor) at UCSF's Department of Obstetrics, Gynecology & Reproductive Science are proposing the Period Pills Study to test a traditional but underutilized framework of menstrual regulation for pregnancy loss, to "bring back" a period when it is late, or missed. This study will aim to recruit 100 participants who have a late period to address research questions that focus on the feasibility and acceptability of using period pills for menstrual regulation.
