If you have sex without a penis in the vagina or if you still use a condom for protection, mifepristone 50 mg can still be used once a week.
However if there is a good chance that there will be no unprotected sex, it is better not to participate in the study. After all, the study must demonstrate that mifepristone works well as a contraceptive. This is only possible if there is regular unprotected sex (without a condom)
