This tool offers general guidance only on missed contraceptive pills. What to do depends heavily on which type of pill you take (combined or progestogen-only), how many you've missed, and where you are in your pack — so the single most reliable source is the patient information leaflet that came with your specific pill.
If you're unsure whether you're still protected, or whether you may need emergency contraception, contact a pharmacist, GP, or family-planning service as soon as you can — they can give advice tailored to your exact situation.
