Period Delay Pills

How Can I Delay My Period?

If you’re looking to delay your period, you’ve come to the right place.

Every month, your body goes through a hormonal cycle controlled by the hormones estrogen and progesterone. During this time, your uterus builds up its lining to prepare for pregnancy. If you don’t get pregnant, the levels of estrogen and progesterone in your body begin to drop. When it reaches a certain threshold, your menstruation will begin.

Menstruation, or your monthly period, refers to when your body gets rid of the monthly buildup of the lining of your uterus, including your unfertilized egg. Tissues and menstrual blood exits your body by passing through your cervix and through your vagina.

A typical menstrual cycle lasts for 28 days. But, each woman is different. Some are “regulars” while others suffer from delayed periods due to hormonal problems or underlying medical conditions.

How to Delay Your Period

There are many reasons why someone may want to delay their period; for example, an upcoming summer getaway or a big event. Whatever your reasons are, you can rest assured that there are proven ways that will help you to delay your period.

The most effective, and safest, way to delay your period is by taking period delay pills. Express Pharmacy stocks Norethisterone, the most popular and effective period delay treatment on the market.

What is Norethisterone?

Norethisterone is a period delay pill that contains a synthetic hormone like progesterone. One of its primary functions is to stop uterine bleeding. It can delay your period by up to 17 days, depending on the course you decide to take. It is also used to treat a number of menstrual cycle problems.

How to Use Norethisterone

This period delay tablet should be taken three times a day, three days before your expected period schedule. Keep taking norethisterone until you want to bleed again, or for a maximum of 20 days. If you miss a dose, consult with your GP.

How Do Period Delay Tablets Work?

Period delay pills work by artificially increasing the levels of progesterone in your body. Remember that a decrease in progesterone levels signals your body to prepare to discharge the uterus’ lining and unfertilized egg - leading to your period.

Hence, by keeping the levels of progesterone high, you delay your period.

What Are the Benefits of Using Period Delay Tablets?

The primary benefit of period delay tablets is the fact that they give you control as to when you start your period. Norethisterone can also help treat:

  • Abnormal vaginal bleeding
  • Endometriosis
  • Anaemia
  • Menstrual disorders

Delaying your period using period delay pills is also worth considering when you have:

  • A physical or mental disability that keeps you from using tampons or sanitary napkins
  • Painful, prolonged, and heavy periods
  • Breast tenderness
  • Bloating
  • Massive mood swings

Some women also delay their period for convenience. If you have an upcoming exam, vacation, wedding, or athletic event, you may opt to delay your period until they’ve passed.

Are There Any Side Effects of Period Delay Tablets?

Like any medicine, period delay tablets also have side effects. Stop taking period delay pills when you experience the following:

  • Swelling of the face and wheezing - this could indicate an allergic reaction to the treatment.
  • Thrombosis - the presence of blood clots in the legs or lungs.
  • Migraines
  • Increasing blood pressure

If you experience any of the symptoms, stop taking norethisterone immediately and contact your doctor.

Below are the common side effects of period delay pills:

  • Premenstrual symptoms
  • Changes in your sex drive
  • Stomach ache
  • Skin rashes (includes itchiness, discolouration or reddening of the skin, blisters, etc.)
  • Dizziness
  • Drowsiness
  • A general feeling of tiredness, being sick
  • Fever
  • Sleeplessness
  • Changes in your appetite
  • High blood sugar levels
  • Ovarian cysts
  • Breast discomfort
  • Vision problems
  • Spotting

As with any type of medication, always follow the doctor’s advice.

We discourage using Norethisterone for prolonged periods. It works great as a once-in-a-blue-moon solution, but it's not intended to be used as a means to delay your period regularly.

When Will My Period Return?

When you stop taking delay pills, the levels of progesterone go back to normal. Normally, you’ll bleed again within 2 to 4 days after taking the last dose of your period delay tablets. This is just an estimate, and the result will vary from one person to another. Give your body some time to readjust its hormone levels.

However, if your period is not back for more than a week after taking your last period delay pill, contact your doctor. They may recommend a pregnancy test to rule out that possibility.

Is Norethisterone a Contraceptive?

It is important to note that Norethisterone is not a contraceptive. This means that it will not stop you from getting pregnant. If you want to protect yourself from unwanted pregnancy, you can take combined pills or use other contraceptive methods (e.g. condoms, spermicides, etc.).

Norethisterone simply contains progesterone, the hormone which controls the discharge of your unfertilized egg and the lining of your uterus during your period. Contraceptive pills, on the other hand, contain hormones that stop you from ovulating. Hence, fertilization is not possible.

Fertilization and pregnancy can still occur when taking period delay tablets because you are simply “delaying” the breakdown of your unfertilized egg and uterine lining.

Our price promise commitment means that as we match prices nationally, prices will go down (and up) accordingly.

If you see or buy a treatment online and find it cheaper with a high street competitor (whether or not they also sell online), as long as their service conditions are comparable, then we’ll match that price for you or refund the difference. The cost of the treatment must include consultation charges for medication without a prior prescription. Comparable service conditions include factors such as delivery charges and timescales (such as Shutl delivery), and consultation charges.

If you’ve already purchased the treatment online, please make sure you report the price match within 28 days of receiving it. If you’d like to buy the product but want us to price match first, please check that you’re providing the most up to date information you can obtain when you submit your claim.

We’ll be asking you for full details of the treatment, the competitor and their prices, so please do check that you have this information to hand before you contact us.

Please note though, that we won’t refund the difference in price paid if you could have bought the product more cheaply with an online-only retailer: examples of this include chemistdirect.co.uk, who sell only through their websites or mail order and not via high street shops. We also don’t match competitors who are in administration or closing down.
