The Progestogen Only Pill or Mini Pill
There are two types of contraceptive pill: the combined pill, and the progestogen-only pill, also known as the 'mini pill'. The progestogen only pill is a daily tablet that contains one hormone: progestogen.
The hormone makes it harder for sperm to get into the uterus (womb) and may also change the lining of the uterus so an egg cannot develop in it. It sometimes prevents an egg from being released by the ovaries each month.
