What is The mini pill?
The mini pill, or progestogen-only pill, is a form of hormonal contraception containing only progestogen, unlike the combined pill which also contains oestrogen. It works mainly by thickening cervical mucus to prevent sperm reaching an egg, and in some types, by also preventing ovulation.
It's taken every day without a break, and unlike some other contraceptive pills, timing can be important, with some types needing to be taken within a strict window each day to remain effective.

BarnMD Bottom Line
The mini pill is a reliable, oestrogen-free contraceptive option, particularly suitable for people who can't take oestrogen-containing pills, such as while breastfeeding.
Taking the mini pill at the same time each day is especially important for it to work effectively, more so than with some other contraceptive pills.
