Progesterone-only pill (POP)

Pire progesterone anake

The progestogen-only pill (POP), often called the mini pill, contains a small amount of the hormone progestogen. It works by thickening your cervical mucus, which stops sperm from getting to the egg. It may also stop your ovaries releasing eggs.

You must take it every day and within three to four hours of the same time each day.

The POP is very good at stopping pregnancy (at least 92% and up to 99% if taken correctly).

Most women can use the POP, including those who can't use the combined oral contraceptive pill. This can include women who are breastfeeding, who get migraines, who have a strong family history of DVT (blood clots) and older women.

The POP has very few side effects. Some women continue to have normal periods, some get irregular bleeding and a small number get no bleeding.

See your general practice, Family Planning Clinic, school clinic or 298 Youth Health to find out if the POP is right for you.

Sexual health visits with your general practice team may be free. Ask your general practice team if you're eligible.

Appointments at Family Planning Clinics are free for New Zealand residents if you're under 22.

298 Youth Health offers free medical care and counselling for those aged 10 to 24.
