Mini-pills are not used as frequently as regular contraceptive pills. This is in part because mini-pills must be taken at the exact same time every day and in part because more than half of the women have disruptions in their menstrual bleedings.
How do they work?
Mini-pills make the mucous in the uterine cervix so viscous that the sperm cannot enter the uterus. The mucous membrane in the uterus is also affected so that if an egg is fertilised it cannot attach. In addition, the ovulation is relieved over time.
Mini-pills should be taken every day at the same time, also while you are menstruating. There are different types of mini-pills.
Safety
If mini-pills are used the correct way there is around 98% chance that the woman does not become pregnant over the course of 12 months. However, mini-pills should be taken at the exact same time every day.
