Types of progestogen-only pill

The mini pill, also called the POP, contains progestogen without oestrogen. Depending on the product, it may thicken cervical mucus, make it harder for sperm to reach an egg, and sometimes prevent ovulation. Common formulations use desogestrel or levonorgestrel. Levonorgestrel is a progestogen material used in some hormonal contraceptives.

The practical difference is the missed-pill window. Some products need very consistent daily timing, while others allow a wider window. Bleeding may become lighter, less predictable, or stop; these changes do not by themselves show whether contraception is working.

Take one tablet every day in the order shown, including during bleeding or a break-free cycle. Read the product instructions because the late-pill window, starting advice, and instructions after vomiting or diarrhoea vary. Medicines and supplements can also affect contraceptive reliability, so mention every product you take.

If you are changing from another method, ask when protection begins and whether you need condoms for a short period. The combined pill contains oestrogen as well as progestogen and is a different option with different suitability considerations.

Arrange medical advice for persistent troublesome bleeding, severe lower abdominal pain, a positive pregnancy test, or symptoms that concern you after missed pills. Seek urgent care for severe pain with faintness, collapse, or heavy bleeding. A clinician can check for pregnancy, infection, medicine interactions, or another cause rather than assuming the pill is responsible.

Ask which active ingredient suits your health history, what counts as a late pill for that exact pack, when protection starts, and what to do after sickness or a missed dose. You can also ask how bleeding changes will be managed and whether another contraceptive would fit your preferences.
