Can You Delay Your Period? UK Planning Guide
The decision and planning guide to period delay in the UK — your options, how to time the course, ordering lead time, and what to expect. For the science of how it works, see the linked Period Delay Facts guide.
▶ Can you delay your period?
Yes. Norethisterone 5mg delays your period for up to 17 days. Order at least 5–7 days before your expected period, start 3 days before, take three times daily. Women on the combined pill can run packs back-to-back instead. Not a contraceptive.

Norethisterone 5mg (for women not on hormonal contraception)
Norethisterone is a synthetic progestogen that prevents the progesterone withdrawal signal that triggers your period. In brief: it keeps the uterine lining in place for as long as you take it. For the full clinical explanation, see: Period Delay Facts: the science.
| Detail | Norethisterone 5mg |
|---|---|
| When to start | At least 3 days before expected period |
| Dose | One 5mg tablet, three times daily |
| Maximum delay | Up to 17 days |
| Period returns | 2-3 days after stopping |
| Contraception? | No — continue your usual contraception |
| Full dosing guide | Norethisterone medication guide |
Critical: Norethisterone cannot stop a period that has already started. You must begin at least 3 days before your expected date.
Combined pill back-to-back (for women already on the pill)
If you take a combined oral contraceptive pill, skip the 7-day pill-free break and start the next pack immediately. This eliminates the withdrawal bleed without any separate prescription. Triphasic or biphasic pills need specific prescriber guidance.
Natural methods
Lemon juice, apple cider vinegar, vigorous exercise, and dietary changes have no reliable clinical evidence for safely delaying periods. Hormonal medication is the only proven method.
How to Plan Your Timing
1
Work out when your period is due
Estimate based on your last 2-3 cycles. If unsure, use your earliest likely date.
2
Order 5-7 days before that date
Complete your online consultation. Orders approved before 3pm Monday-Friday are dispatched same day via Royal Mail Tracked 24. Allow 1-2 working days for delivery.
3
Start taking norethisterone 3 days before your expected period
One 5mg tablet, three times daily. For step-by-step instructions see: How to take norethisterone.
4
Continue for the duration you need
Take for as many days as needed, up to a maximum of 20 days.
5
Stop when ready
Your period will arrive 2-3 days after your last tablet.
What to Expect After Stopping
Your period usually arrives 2-3 days after your last tablet, occasionally up to a week. It may be slightly heavier or longer than usual — the lining has been maintained for longer. Around 1 in 10 women experience light spotting while taking norethisterone; this is not treatment failure. Your cycle returns to normal within 1-2 cycles.
For a full breakdown of potential side effects and when to seek medical advice, see: Norethisterone side effects guide.
Planning for a Holiday or Event
Period delay is most commonly requested for holidays, weddings, and sporting events. The most important rule is lead time — order well before your trip, not at the last minute. For detailed advice on timing your course around travel, packing for holidays abroad, and swimming, see: Period delay for holiday or event: how to plan ahead.

Order Norethisterone →Frequently Asked Questions
Can you really delay your period?
Yes. Norethisterone 5mg is a safe and effective prescription tablet that delays your period for up to 17 days when started at least 3 days before the expected date. Women already on the combined pill can run packs back-to-back to skip the withdrawal bleed. Natural methods have no reliable clinical evidence.
How far in advance do I need to start norethisterone?
You must start norethisterone at least 3 days before your expected period. In practice, order 5-7 days before your expected start date to allow for consultation review and delivery. Orders approved before 3pm Monday-Friday are dispatched same day via Royal Mail Tracked 24.
What are the options for delaying a period?
Two main options: norethisterone 5mg (prescription tablet, for women not on hormonal contraception) or running combined pill packs back-to-back (for women already on the pill). Natural methods — lemon juice, exercise, dietary changes — have no reliable clinical evidence.
Will my period be heavier after delaying it?
Slightly heavier or longer in some women, as the uterine lining has been maintained for longer. This is expected and not a cause for concern. Your cycle returns to normal within 1-2 cycles.
Is period delay suitable for swimming and holidays abroad?
Yes. Norethisterone is an oral tablet — swimming, water sports, and travel have no effect on how it works. It works the same way regardless of location. For full travel planning guidance see our period delay for holiday guide.
