How to Delay Your Period Naturally: What Actually Works
Lemon juice, apple cider vinegar, gram lentils, exercise and other popular remedies: what the evidence says, why they don’t work on demand, and the medical options that do.
Part of the Period Delay Health Guide.
When to get urgent help: Call 999 or go to A&E if you have signs of a blood clot or stroke while taking norethisterone: pain, swelling or redness in one leg; sudden chest pain or breathlessness; coughing up blood; sudden weakness or numbness on one side of the body, difficulty speaking or a sudden severe headache. Also call 999 for a severe allergic reaction, such as swelling of the face, lips, tongue or throat, wheezing or difficulty breathing. Stop taking it and see a doctor the same day if your skin or eyes turn yellow, you get a migraine for the first time, or you have sudden changes to your vision.
Key fact: there is no reliable evidence that any food, drink or home remedy delays a period on demand. The reliable options are medical: norethisterone 5mg tablets, or running a combined pill back to back if you already take one.
Search “delay period naturally” and you’ll find lemon juice, apple cider vinegar, gram lentils and plenty more. Here’s an honest look at what the evidence shows, what can genuinely change the timing of a period (though not in a way you can control), and the medical options if you need to move a period for a fixed date.

| Method | What’s claimed | What the evidence says |
|---|---|---|
| Lemon or lime juice | Delays or lightens bleeding | No clinical evidence. Large amounts of acidic juice can irritate your stomach and wear tooth enamel |
| Apple cider vinegar | Delays your period | No evidence it changes the timing of a period. Undiluted vinegar can damage teeth and the throat |
| Gram lentils, fenugreek and other foods | Traditional remedies to delay bleeding | No reliable studies |
| Intense exercise | Holds off your period | Very intense training can disrupt cycles over weeks or months, but it can’t postpone a specific period, and training to that point can harm your health |
| Herbal supplements | Various | No reliable evidence. Some herbal products, such as St John’s wort, interact with hormonal medicines including norethisterone and the pill |
Why natural methods can’t move a period on demand
Your period starts when your progesterone level falls at the end of your cycle. To delay it, progesterone has to stay high, and that is exactly what norethisterone, a man-made progestogen, does. No food or drink meaningfully raises your progesterone level, so home remedies can’t reliably move your period.
Things that can change your cycle, but not reliably
According to the NHS, stress, sudden weight loss, being overweight and doing a lot of exercise can all make periods late or stop them. These are not ways to delay a period: the effect is unpredictable, it can’t be timed for a particular date, and pushing your body that hard isn’t good for you. If your periods have changed because of weight loss, low eating or very heavy training, speak to your GP.
What actually works
- Norethisterone 5mg: one tablet three times a day, starting at least 3 days before your period is due, for as long as your prescriber advises. Your period usually starts within 3 days of stopping. It is suitable for most healthy women after a prescriber check, but it carries a small risk of blood clots. See how norethisterone works.
- Combined pill back to back: if you already take a combined pill, you can usually skip the pill-free break. See delaying your period on the pill.
- Medroxyprogesterone tablets: an off-label option a prescriber may suggest if norethisterone isn’t suitable. See period delay options compared.
If you’d rather not take anything
That’s a completely valid choice. If the timing isn’t critical, period pants, a menstrual cup or tampons can make a holiday or event more comfortable without delaying anything, and anti-inflammatory painkillers such as ibuprofen can ease cramps if they are suitable for you. If you genuinely need to avoid bleeding on a fixed date, a medical option is the only reliable route.
If your period is late and you weren’t trying to delay it
If you could be pregnant, take a pregnancy test. If the test is negative and your period still hasn’t come, or your periods have stopped or become irregular, speak to your GP. Stress, weight changes, exercise, some contraceptives and conditions such as polycystic ovary syndrome can all affect your cycle.
UK safety and prescribing information
- Legal status: norethisterone is a prescription-only medicine (POM). At Access Doctor it is prescribed only after an online consultation with a GPhC-registered pharmacist independent prescriber, who may decline and suggest an alternative or that you see your GP.
- Licence: it is the only progestogen licensed in the UK to delay periods (NHS Specialist Pharmacy Service). The dose is 5mg three times a day, starting 3 days before your period is due.
- Course length: take it for as long as your prescriber advises. The Primolut N licence describes courses of no longer than 10 to 14 days, and NHS Specialist Pharmacy Service guidance says it can be taken for up to 3 to 4 weeks if necessary.
- Not a contraceptive: use condoms or another method while you take it.
- Blood clots: part of each dose is converted in the body to ethinylestradiol, the oestrogen in the combined pill (about 4–6 micrograms for every 1mg, according to the Primolut N product information), so the same blood clot warnings apply. Your prescriber will check risk factors such as a previous clot, smoking, a BMI over 30, being over 35, recent surgery and long-haul travel.
- Pregnancy and breastfeeding: do not take it if you are or might be pregnant. The Primolut N product information says it should be avoided while breastfeeding, so ask your prescriber.
- Reporting side effects: you can report suspected side effects to the MHRA through the Yellow Card scheme website or the Yellow Card app.
