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. Certain options, like ulipristal acetate (EllaOne), 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 varieties available:- Levonorgestrel (Levonelle-1): Ideally ingested within 72 hours, it functions by temporarily postponing ovulation, the release of an egg from the ovary.
- Ulipristal acetate (EllaOne): Effective for as long as 120 hours (5 days) and could be marginally more effective later in your cycle. Accessible only through a prescription.
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: Levonorgestrel-based pills (such as Levonelle-1) remain effective.
- Within 5 days: Ulipristal acetate (EllaOne) continues to be effective but requires a prescription.
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.
Experiencing these symptoms? Speak with a doctor within 15 minutes.
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

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.15 minutes, anytime, anywhere.
