Start your consultation →Can You Delay Your Period?
Yes. A period starts when progesterone levels fall at the end of your cycle, signalling the womb lining to shed. Keep progesterone artificially elevated and you postpone that signal. The proven ways to do this are hormonal: a course of norethisterone tablets, or — if you are already on the combined pill — running packs back-to-back. Natural methods (lemon juice, apple cider vinegar, exercise) have no reliable evidence. See the full decision guide: Can you delay your period? Your options.

How Norethisterone Works
Norethisterone is a synthetic progestogen that mimics progesterone, holding the womb lining in place for as long as you take it. When you stop, progesterone falls and your period arrives within 2–3 days. It cannot stop a period that has already started — you must begin at least 3 days before your expected date. See the complete norethisterone for period delay guide, and the step-by-step schedule.
How to Plan the Timing
Work out your expected date from your last 2–3 cycles, order 5–7 days ahead, start 3 days before, take for as long as you need (up to 20 days), then stop. Orders approved before 3pm Monday to Friday are dispatched same day. Planning around a trip or event? See period delay for holidays and events, or for Ramadan, Hajj, Umrah or exams.
Is It Safe? Who Can and Can't Use It
Occasional period delay is safe for most healthy women. It is not suitable if you are pregnant or breastfeeding, or have a history of blood clots (DVT/PE), severe liver disease, hormone-sensitive cancer, or unexplained vaginal bleeding. Your prescriber checks suitability during the consultation. Read the full picture: Is it safe to delay your period?
Check suitability first: Norethisterone isn't suitable for everyone. Always give your full medical history at consultation so your prescriber can confirm it's right for you.
Side Effects
Most women tolerate short courses well. Common effects: breast tenderness, bloating, nausea, headache, mood changes and light spotting (~1 in 10). See the full norethisterone side effects guide, and can you drink while taking norethisterone?
Seek emergency attention: Stop and call 999 for chest pain, breathlessness or severe leg pain — possible signs of a blood clot.
Cost
Norethisterone starts from £13.99 (30 tablets), which includes your online consultation, prescription, medication and delivery. Medroxyprogesterone starts from £16.99. Full pricing: How much does period delay cost?
