Yes, there is a pill specifically designed to delay your period. The most commonly used one is norethisterone, a synthetic form of progesterone that keeps your uterine lining stable so it doesn’t shed on schedule. If you’re already on combined birth control pills, you also have the option of skipping your placebo week to push your period back. Both approaches work, but they differ in how you access them, how you take them, and how reliably they prevent bleeding.
How Norethisterone Works
Norethisterone mimics the progesterone your body naturally produces in the second half of your menstrual cycle. Normally, progesterone levels drop right before your period, signaling the uterine lining to break down and shed. By taking norethisterone, you keep progesterone levels artificially elevated, which holds the lining in place and prevents bleeding from starting.
The standard dose is 5 mg taken two or three times a day. You need to start 3 to 5 days before your expected period, and you can continue for up to 14 days. Once you stop taking the pills, your period will typically arrive within 2 to 3 days. This makes the timing fairly predictable, which is useful if you’re planning around a specific event.
One Important Distinction: It’s Not Birth Control
Norethisterone at the dose used for period delay is not a reliable contraceptive. While a much lower dose of the same drug is used in some progestogen-only birth control pills, the period delay regimen isn’t designed or tested for pregnancy prevention. If you’re sexually active and not using another form of contraception, you’ll need separate protection while taking it.
Skipping Placebo Pills on Birth Control
If you’re already taking combined oral contraceptive pills, you have a simpler option. Instead of taking the inactive (placebo) pills during week four, you start a new pack of active pills immediately. The hormones in those active pills suppress ovulation continuously, so your body never gets the hormone drop that triggers a period.
The American College of Obstetricians and Gynecologists confirms this is safe: getting fewer periods through continuous pill use is normal and healthy. You can do this for one cycle to skip a single period, or you can continue the pattern long term. The main trade-off is that you’ll go through pill packs faster, meaning more frequent refills. Not all insurance plans cover the extra packs without pushback.
This approach does come with a learning curve for your body. Breakthrough bleeding, or light spotting between periods, is common in the early months. In one clinical trial, only about 50% of women on continuous pills had no bleeding by their third pack. That number improved to around 69% by pack seven and 88% by cycle twelve. So if you’re trying this for a one-time event, there’s roughly a coin-flip chance of some spotting the first time. Pills with higher estrogen doses tend to produce more reliable suppression than low-dose formulations.
Side Effects to Expect
The most common side effects of norethisterone are breast tenderness and nausea. These are typically mild and resolve once you stop taking the medication. Some people also notice mood changes, including low mood or irritability, which makes sense given that you’re altering your hormone levels. Severe side effects are rare but include signs of liver problems (upper belly pain, dark urine, yellowing skin) or gallbladder issues. If those appear, stop the medication and get medical attention.
Spotting or light breakthrough bleeding can still happen while taking norethisterone, even though the whole point is to prevent bleeding. It’s not guaranteed to work perfectly for everyone, and setting realistic expectations matters. Complete suppression of all bleeding is the goal, but some people experience minor spotting despite taking the pills correctly.
Who Shouldn’t Take Period Delay Pills
At the therapeutic dose used for period delay, norethisterone has both progestogenic and estrogenic effects in the body. That gives it a similar risk profile to combined hormonal contraceptives when it comes to blood clots. You should avoid norethisterone if you have a personal history of blood clots (deep vein thrombosis or pulmonary embolism), a strong family history of clotting disorders, a known clotting condition, or if you’re about to have surgery that requires immobilization. Obesity and limited mobility also increase the risk. For people in these categories, a doctor may suggest medroxyprogesterone acetate as a safer alternative.
How to Get It
Access depends on where you live. In the United States, norethisterone (sold as norethindrone) requires a prescription from a healthcare provider. There is no over-the-counter period delay pill available in the US.
In the UK, the landscape has shifted recently. NHS England issued guidance stating that GPs should no longer routinely prescribe norethisterone for non-medical reasons like holidays or weddings. Instead, people looking to delay a period for lifestyle reasons can access it through community pharmacies that offer pharmacist consultations, private clinics, or online doctor services. These typically involve a short questionnaire or consultation to screen for contraindications before dispensing the medication.
If you’re already on combined birth control and just want to skip one period, you don’t need a separate prescription. You simply start your next pack early. It’s worth letting your prescriber know so they can help coordinate refills, but the method itself doesn’t require a new medication.
Planning the Timing
If you’re using norethisterone for a specific event, count backward from when you need to be period-free. Start the pills 3 to 5 days before your period is due, and plan to keep taking them through the event. Your period will come 2 to 3 days after your last pill, so factor that into your schedule too. If you need more than 14 days of delay, talk to a prescriber, as the standard recommendation caps the course at two weeks.
For the birth control skip method, you need at least one full extra pack on hand. If your event is months away, consider doing a trial run first. Starting continuous use a few cycles early gives your body time to adjust, reducing the chance of breakthrough bleeding when it actually counts.
