How this medication works

The mini-pill contains progestin only (no estrogen). It primarily works by thickening cervical mucus, which helps block sperm from reaching an egg. Depending on the specific pill type, it may also suppress ovulation.

The mini-pill can be a great option for people who should avoid estrogen (including many breastfeeding patients). Timing matters more with this pill than with combination birth control.

How to take it

• Take one pill every day, at the same time each day
• There are no placebo pills in most mini-pill packs, so you take pills continuously
• If you are more than 3 hours late taking a dose (for traditional progestin-only pills), protection may be reduced
• If you are late or miss a pill: take the missed pill as soon as you remember, then take your next pill at the usual time (this may mean taking 2 pills in one day)
• Use backup protection (condoms) for the next 3 days (72 hours) if you are 3 hours or more late/miss a pill
• If you start the mini-pill outside the first 5 days of your period, use backup protection for 3 days (72 hours)

Tip: set a daily phone alarm. Consistency is the secret sauce for the mini-pill.

What to expect

• Spotting or irregular bleeding is common, especially in the first 1–3 months
• Some people notice lighter periods, or periods may stop altogether
• Mild breast tenderness, acne changes, or mood changes can occur as your body adjusts

If bleeding is heavy (soaking a pad/tampon every hour), you have severe pain, or you feel faint or unwell, seek urgent evaluation.

Important safety information

• Because timing is critical, late pills can quickly reduce protection
• The mini-pill does not protect against sexually transmitted infections (STIs)
• If you have vomiting/diarrhea or start new medications, effectiveness may be affected. Message us if you’re unsure.
• If you think you may be pregnant or miss a period after late/missed pills, take a pregnancy test and contact us
