Study how metabolism differences affect emergency contraception
Treatments studied
Part of Women’s health & pregnancy clinical trials.
This trial looks at whether differences in how your body processes a certain emergency contraceptive can change how well it works. You may be asked to provide a progesterone blood test during your cycle to confirm that ovulation is happening.
