This myths and facts guide will help you understand what emergency contraceptive pills do, what they do not do, and whether they can cause infertility.
What Are Emergency Contraceptive Pills?
Emergency contraceptive pills are used to reduce the chance of pregnancy after unprotected sex or contraceptive failure. This could include situations such as a condom splitting, missed pills, or a delayed contraceptive injection.
Emergency contraception works best when taken as soon as possible. There are different types available, and the right option can depend on timing, your cycle, and any medicines you take.
Emergency contraceptive pills are designed for occasional use. They are not intended to replace regular contraception, but they can be a safe and effective backup when something goes wrong.
Myth vs Fact: Do Emergency Contraceptive Pills Cause Infertility?
Myth: Emergency contraceptive pills cause infertility
Fact: There is no evidence that emergency contraceptive pills cause infertility
This is the key question many people worry about, and it is important to be clear. Emergency contraceptive pills do not cause permanent changes to your fertility. They do not damage your ovaries, your womb, or your ability to get pregnant in the future.

Emergency contraceptive pills work by temporarily affecting hormones and ovulation timing. This is a short-term effect, and it does not stop your body from returning to its normal cycle afterwards.
In fact, it is possible to become pregnant very soon after taking emergency contraception, which is why ongoing contraception matters.
If you are worried about your fertility, or your cycle feels unusual after taking emergency contraception, reach out to us to book and we can advise you on next steps.
Myth vs Fact: Emergency Contraceptive Pills Are The Same As An Abortion Pill
Myth: Emergency contraception ends an existing pregnancy
Fact: Emergency contraceptive pills do not end an existing pregnancy
This is a common misunderstanding. Emergency contraceptive pills like ellaOne and Levonelle are not the same as abortion medication. They are designed to prevent pregnancy from happening, not to end a pregnancy that has already implanted.
Emergency contraception mainly works by delaying or preventing ovulation. If ovulation does not happen, there is no egg to fertilise, which reduces the chance of pregnancy.
If you think you may already be pregnant, it is still worth speaking to a healthcare professional for advice. Contact us to book if you are unsure.
Myth vs Fact: You Can Only Take Emergency Contraception Once
Myth: You can only take emergency contraception once in your life
Fact: You can take emergency contraceptive pills more than once, but they are not meant for regular use
Taking emergency contraceptive pills occasionally is considered safe for most people. However, they can cause temporary changes in your cycle, and they are not as effective as regular contraception when used repeatedly.
If you find you need emergency contraception more than once, it may be a sign that your current method is not working well for you. In that case, it can help to discuss longer-term options.
Myth vs Fact: Emergency Contraceptive Pills Always Work
Myth: Emergency contraceptive pills are 100 percent effective
Fact: No emergency contraception is 100 percent effective, but taking it quickly improves success
Emergency contraceptive pills reduce the chance of pregnancy, but they do not guarantee prevention. Effectiveness depends on factors such as how soon you take it and whether you have already ovulated.
Reasons emergency contraception may be less effective include:
–> Taking it too late after unprotected sex
–> Vomiting soon after taking the tablet
–> Certain medicines that affect absorption or hormone levels
–> Higher body weight, depending on the option used
If you are unsure whether it worked, or your period is late, contact us to book and we can advise you on pregnancy testing and next steps.
Myth vs Fact: It Will Mess Up Your Cycle For Months
Myth: Emergency contraception ruins your hormones long-term
Fact: Your cycle may change temporarily, but it usually settles quickly
After taking emergency contraception, it is normal for your next period to be slightly earlier or later than usual. Some people also notice spotting, mild cramps, or breast tenderness.
Common short-term effects can include:
–> Nausea
–> Headache
–> Temporary changes to bleeding patterns
–> Mild abdominal discomfort
These effects are usually mild and settle without treatment. If symptoms are severe or ongoing, it is important to seek advice.
What To Do After Taking Emergency Contraceptive Pills
After taking emergency contraception, the next steps are often just as important as the dose itself. This is because you can still become pregnant if you have unprotected sex again later in the same cycle.

Here are practical steps to follow:
–> Use condoms until your regular contraception is reliable again
–> Take a pregnancy test if your period is more than 7 days late
–> Seek urgent advice if you have severe lower abdominal pain
–> Consider discussing ongoing contraception options
