Overview

Unprotected intercourse or a contraceptive mishap can lead to anxiety, but emergency contraception can provide reassurance. The morning-after pill is effective in preventing pregnancy when taken as soon as possible, ideally within 72 hours. Knowing how it functions, the expected aftermath, and when to seek assistance can empower you. Emergency contraception, are effective for up to five days following unprotected intercourse. However, prompt usage enhances its effectiveness.

What is the morning-after pill

The morning-after pill represents a type of emergency contraception designed to avert pregnancy after unprotected intercourse or a contraceptive failure, such as a broken condom or missed birth control pill.

How does it work?

In Australia, there are two primary types of emergency contraceptive pills available:

• The 72-hour pill: Ideally taken within 3 days (72 hours) of unprotected intercourse. It functions by temporarily postponing ovulation—the release of an egg from the ovary.

• The 5-day prescription pill: Effective for up to 120 hours (5 days) after unprotected intercourse and may be recommended by a doctor depending on your specific circumstances. This option requires a clinical assessment and a prescription.

Both types of emergency contraception either prevent or delay ovulation; they do not terminate an existing pregnancy or harm a developing embryo. They are intended for infrequent emergencies and do not offer protection against sexually transmitted infections (STIs).

How soon should you take the morning-after pill?

Timing is crucial. The effectiveness of emergency contraception diminishes the longer you delay taking it.

• Within 24 hours: Most effective, reducing the chances of pregnancy by up to 95%.

• Within 72 hours: The standard emergency contraceptive pill remains effective.

• Within 5 days: Certain prescription emergency contraception options continue to be effective but require a medical assessment.

If you are uncertain about which method suits you or if you cannot reach a pharmacy promptly, an online consultation with a medical practitioner can provide you with appropriate guidance and a clinical assessment for a prescription within a few minutes.

How effective is the morning-after pill?

The effectiveness of emergency contraception depends largely on how soon it is taken after unprotected intercourse:

• The 72-hour emergency contraceptive pill: Between 85% and 98% effective, with higher efficacy the sooner it is taken.

• The 5-day prescription pill: Up to 99% effective if administered within 120 hours (5 days).

It may be less effective if ovulation has already occurred. Some prescription options may be more effective for individuals with a higher BMI.

Is it safe?

The morning-after pill is generally deemed safe for the majority of individuals, used globally, and it does not impact future fertility.

What happens after taking the morning-after pill?

Every experience varies, but most individuals only encounter mild, temporary side effects.

• Physical effects: You may experience some nausea, fatigue, or breast tenderness. Others might also feel mild abdominal discomfort, dizziness, or a temporary headache.
• Cycle changes: Your next menstruation could arrive earlier or later than expected. It may also be heavier, lighter, or come with light spotting in the days following the pill.
• Emotional impact: Feeling a blend of relief and anxiety after taking emergency contraception is common, particularly if it follows a distressing event. Such feelings are normal and generally subside once your next period occurs.

These changes are temporary and typically resolve within a few days. If any symptoms persist or worsen, consulting a healthcare provider is advisable.

Possible side effects

Most side effects are mild and of short duration, but being aware of what's normal can help you feel ready. Common effects include:

• Nausea or slight vomiting
• Headaches or dizziness
• Fatigue
• Tenderness in the breasts
• Menstrual timing or flow alterations
• Mild discomfort in the lower abdomen

If you vomit within three hours of taking the pill, consult a doctor; you may require another dose.

When it may not work well

Here are some circumstances where the pill’s effectiveness could be diminished.

• If ovulation has already happened
• Certain medications can lower the effectiveness
•  Higher BMI (LNG may be less effective)
•  Vomiting within 2 hours after taking it

Regular contraception method

The morning-after pill is intended for emergencies and not for regular use. If you frequently find yourself in need of it, think about transitioning to a consistent, long-term contraceptive method. Options include:

1. The daily birth control pill
2. Contraceptive implant or injection
3. Intrauterine device (IUD)
4. Vaginal ring or patch

Discussing these options with a doctor ensures you find what aligns with your lifestyle and health requirements. Telehealth makes it simple to explore these alternatives discreetly and obtain prescriptions if necessary.

What to do after taking it

Here’s what to anticipate and how to safeguard yourself afterwards.

1. Your subsequent period might arrive earlier or later than expected
2. Utilise condoms until your next menstrual cycle
3. Take a pregnancy test if your period is over a week late
4. Initiate or switch to long-term contraception if necessary

When to see a doctor

Consult a doctor if you experience:

• Severe or ongoing abdominal discomfort
•  Heavy bleeding, dizziness, or faintness
•  A period that is more than a week late
•  Any rash, swelling, or breathing difficulties (possible allergic reaction)
•  Vomiting shortly after taking it
•  Positive pregnancy test result
•  Concerns regarding ongoing contraception

These symptoms could signal complications or, in rare cases, an undiagnosed pregnancy. If you are unsure whether your symptoms are typical, a  telehealth consultation can provide reassurance without the need to leave your home. Note: If you experience severe, one-sided abdominal pain, heavy bleeding that soaks through pads every hour, or feel faint, call 000 or visit your nearest Emergency Department immediately.

FAQs

Can the morning-after pill postpone your period?

Yes, it can cause your period to arrive either earlier or later than usual. Most people revert to their normal cycle by the following month.

How long does bleeding last after taking the morning-after pill?

Light bleeding or spotting may last a few days. Heavy or prolonged bleeding should be checked by a doctor.

Is the morning-after pill effective for everyone?

It’s highly effective when taken promptly. However, certain medications, body weight, or health conditions can slightly reduce its effectiveness. Your doctor can help determine the best option for you.

Can you get pregnant again after taking the morning-after pill?

Yes. The morning-after pill only protects against pregnancy from the specific unprotected incident that prompted you to take it. It does not continue to work afterwards. If you have unprotected sexual intercourse again in the following days or weeks, there is still a risk of becoming pregnant. It’s wise to initiate a regular contraceptive method as soon as possible for continuous protection.

When can I expect my period after using the morning-after pill?

Your period might come a few days earlier or later than your anticipated date. The hormones in the morning-after pill can temporarily influence your menstrual cycle, but most individuals typically return to their usual rhythm within a month. It's also common to experience spotting or light bleeding before your actual period. If your period is more than seven days late, it's advisable to take a pregnancy test to ensure that the pill worked effectively.

When should you take a pregnancy test after the morning-after pill?

If your period hasn't started within a week of when it was expected, take a pregnancy test. For the most accurate results, it’s best to use a first-morning urine sample when hormone levels are at their peak. If the test result is negative but your period does not arrive after a few more days, consider retesting or consulting with a doctor online for further guidance. Telehealth doctors can assist you with testing, help evaluate your symptoms, and advise on the next steps if you’re uncertain about the test results.
