Bleeding after taking the emergency contraceptive pill is related to the time and amount of bleeding. If the bleeding is very light and short, it does not necessarily mean that you are not pregnant. If the bleeding occurs exactly one week after taking the pill, and the amount of bleeding is similar to your usual period, then it is withdrawal bleeding, which means the pill is successful. However, it is best not to take the emergency contraceptive pill too often, because it has more side effects and cannot be taken continuously, which can lead to irregular periods and irregular bleeding, and can cause a delay in the next menstrual period, so the healthiest way is to use condoms.
