    “You may be eligible to help researchers learn more about the most effective way to use estrogen-free birth control pills!”

    open to eligible females ages 18-35

    Norgestrel 75 mcg is a progestin-only pill (POP), which is a kind of oral birth control pill. To be effective in preventing pregnancy, this kind of birth control pill is supposed to be taken every day at the same time, without delaying the intake for more than 3 hours. This study aims to find out if taking the pill 6 hours late or not taking it for one day will affect the way it works.
