5 Myths About the Morning After Pill Every Aussie Should Know

5 Myths About the Morning After Pill Every Aussie Should Know

Seventy per cent of Australian women say they haven’t had enough education about contraception – and more than a third report a pregnancy scare, with 38% saying they’ve used emergency contraception at least once.

At the same time, Australian research has found that about a third of women have used emergency contraception, yet misinformation is still rampant – including that it’s “an abortion pill” or that it will “ruin your fertility”.

If you’ve ever Googled “morning after pill myths”, “Plan B side effects”, or “emergency contraception Australia” at 2am after a broken condom, you’re definitely not alone.

In this article, we’ll unpack five of the biggest myths about the morning after pill in Australia, using evidence-based reproductive health facts – not scare stories. We’ll also explain how emergency contraception actually works, what to expect, and how online contraception prescription services (like ours at NextClinic) can fit into your broader sexual health plan.

This article is general information only and not a substitute for personalised medical advice. If you’re worried about pregnancy or side effects, it’s always worth talking to a GP or one of our telehealth doctors.

Quick refresher: What is the morning after pill in Australia?

Before we bust the myths, it helps to be clear on what we’re talking about.

In Australia, when people say “the morning after pill” or “Plan B”, they usually mean emergency contraception pills (ECPs) – medicines taken after sex to reduce the chance of pregnancy when your usual contraception wasn’t used, failed, or you were sexually assaulted.

You have three main emergency contraception options in Australia:

  1. Levonorgestrel pill (LNG ECP)
    • Take as soon as possible, up to 3 days (72 hours) after unprotected sex; there may still be some benefit up to about 4 days.
    • Sold over the counter at pharmacies (no prescription).
    • Often what people mean when they say “Plan B” (even though that brand name isn’t sold here).
  2. Ulipristal acetate pill (UPA ECP)
    • Single tablet, taken any time up to 5 days (120 hours) after sex.
    • More effective than levonorgestrel later in that 5‑day window.
    • Available from pharmacies after a discussion with the pharmacist, no separate GP script usually needed in Australia.
  3. Copper intrauterine device (copper IUD)
    • Inserted by a trained doctor or nurse within 5 days of unprotected sex.
    • Most effective form of emergency contraception (>99% effective), and then works as long‑term contraception for 5–10 years depending on the device.

All of these methods work best the sooner you use them, and none of them protect against sexually transmissible infections (STIs).

At NextClinic, we regularly help patients decide which option makes sense for them, and we can also arrange quick scripts and referrals if you want to move from “emergency-only” to a reliable long-term method (like the pill, implant, or IUD).

Now, let’s tackle the myths.

Myth 1: “The morning after pill is an abortion pill”

This is probably the most common – and most emotionally loaded – myth.

The truth: It prevents pregnancy; it doesn’t end an existing one

Medical bodies from the World Health Organization to Australian health agencies are very clear: emergency contraception pills work mainly by delaying or preventing ovulation (the release of an egg). If there’s no egg, sperm can’t fertilise it, so pregnancy can’t start.

Key points:

  • If you’re already pregnant, emergency contraception won’t work and won’t end the pregnancy.
  • It does not dislodge an embryo that has already implanted in the uterus.
  • International reviews have found no evidence that levonorgestrel ECPs prevent implantation; their main (and possibly only) effect is before fertilisation.

By contrast, medical abortion uses completely different medicines (such as mifepristone plus misoprostol) to end an established pregnancy. That’s a separate process with its own laws, timeframes, and medical protocols in Australia.

So why do so many people still think the morning after pill is “basically an abortion”?

An Australian national survey of women aged 16–35 found that about one in three believed the emergency contraceptive pill was an abortion pill. This misconception can stop people from seeking help quickly after unprotected sex – exactly when emergency contraception works best.

Takeaway

If you’re not ready for a pregnancy, taking the morning after pill after a slip‑up is a way to prevent needing an abortion later, not a type of abortion itself.

Myth 2: “The morning after pill will make you infertile”

You’ve probably heard some version of this: “If you keep taking Plan B, you’ll never be able to have kids,” or “It messes up your hormones forever.”

The truth: No evidence of long‑term harm to fertility

Global health authorities and reproductive health specialists are very clear: emergency contraception does not cause infertility.

Here’s what the evidence shows:

  • The hormones in levonorgestrel or ulipristal temporarily disrupt your normal cycle to delay or prevent ovulation.
  • Fertility returns quickly after use – usually by your next cycle.
  • An Australian fertility and gynaecology clinic summarised the data: the morning after pill does not affect long‑term fertility, and there’s no evidence it makes it harder to conceive in the future.

The World Health Organization also states that drugs used for emergency contraception do not harm future fertility, and there’s no delay in the return to fertility after taking emergency pills.

So why does this myth cling on? A few reasons:

  • Cycle changes (like a late period or spotting) after taking ECPs are common, and easy to misinterpret as “damage”.
  • Social media is full of anecdotal stories that sound scary but don’t reflect the broader evidence.
  • Many people simply don’t get clear, science‑based explanations of what the drug is doing.

What can happen?

You might notice for a cycle or two:

  • A period that’s a bit earlier or later than usual.
  • Slightly heavier or lighter bleeding.
  • Some spotting.

These are short‑term hormonal effects, not permanent changes to your reproductive system.

Takeaway

Using emergency contraception – even more than once – won’t “use up” your fertility or stop you from having children in the future. If pregnancy is something you want later on, protecting yourself from an unplanned one now is part of looking after your future reproductive health.

Myth 3: “You have to take it the next morning or it won’t work”

The name “morning after pill” doesn’t help here. It sounds like there’s a 12‑hour deadline and then… game over.

The truth: You usually have several days – but sooner is always better

In Australia:

  • Levonorgestrel ECPs are recommended up to 72 hours (3 days) after unprotected sex, and may still have some effect up to about 96 hours.
  • Ulipristal acetate ECPs can be used up to 120 hours (5 days) after sex and are generally more effective than levonorgestrel later in that window.
  • Copper IUDs can be inserted within 5 days and are the single most effective form of emergency contraception.

International data show that when taken correctly within recommended timeframes, emergency pills can prevent the vast majority of pregnancies that would otherwise occur – but their effectiveness drops the longer you wait.

So if you’re reading this just a few hours after unprotected sex, you absolutely haven’t “missed your chance”. Even if you’re on day 3 or 4, it may still be worth talking to a pharmacist or doctor right away to see which option fits your timing and circumstances.

Why the urgency still matters

Every hour you hesitate:

  • You might miss the sweet spot for the levonorgestrel pill.
  • You might narrow your options (for example, ulipristal vs copper IUD).
  • Anxiety tends to spiral – and that stress doesn’t help anyone.

For many people, having a “Plan B” on hand at home can dramatically cut down on that panic. Some pharmacists and telehealth services support advance provision of emergency contraception so you’re not racing around to find an open chemist when you’re already stressed.

Takeaway

It’s not “this morning or nothing”. But the earlier you act, the better your chances. If in doubt, go now, not tomorrow.

Myth 4: “Plan B side effects are always severe or dangerous”

Search “Plan B side effects” and you’ll find plenty of horror stories. It’s no wonder many Australians are hesitant, especially when 42% of women say a fear of side effects stops them from trying a new contraceptive at all.

The truth: Most side effects are mild and short‑lived

According to Australian state health services and the WHO, the most common side effects of emergency contraception pills are:

  • Nausea (feeling sick)
  • Vomiting (if this happens within 2–3 hours, you may need another dose – ask a pharmacist or doctor)
  • Headache
  • Dizziness or fatigue
  • Breast tenderness
  • Mild tummy cramps
  • Spotting or changes in your next period’s timing and flow

These effects:

  • Usually last a day or two, sometimes just a few hours.
  • Don’t mean the medicine is “damaging” your body.
  • Generally don’t require ongoing treatment.

WHO notes that these side effects are not common, usually mild, and resolve without further medication.

Serious side effects are very rare

Like all medicines, emergency contraception isn’t completely risk‑free. For people with certain health conditions (for example, specific clotting disorders or uncontrolled severe liver disease), some hormonal methods might not be recommended as a regular contraceptive – but there are no absolute medical contraindications to using emergency contraception once.

If you have a complex medical history or are on medications that interact with hormones (such as some epilepsy or TB drugs), it’s a good idea to check in with a GP or telehealth doctor. They can confirm which option (levonorgestrel, ulipristal, or copper IUD) is safest and most effective in your situation.

What about birth defects?

Another common fear is: “What if I was already pregnant and didn’t realise – could the morning after pill harm the baby?”

Studies and expert reviews have not found an increase in birth defects among people who took emergency contraception and were already pregnant.

Takeaway

For most Australians, emergency contraception pills are very safe, with short‑term, manageable side effects. The risk of an unplanned pregnancy is almost always far more significant than the temporary discomfort of the medication.

Myth 5: “You can only use the morning after pill once – more than that is dangerous or won’t work”

This myth often shows up as: “You’re only allowed to take it three times in your life,” or “If you use it twice in one cycle it stops working.”

The truth: Repeat use is medically safe – but not a good main contraceptive strategy

The World Health Organization is explicit:

  • Repeated use of emergency contraceptive pills poses no known health risks.
  • It can cause more frequent side effects like cycle irregularities, but doesn’t damage your fertility.

Healthdirect – the Australian government‑funded health website – likewise notes that the morning after pill does not have long‑term effects and can be used more than once in a cycle if needed.

So medically speaking, if you’ve had two separate “uh‑oh” moments in one month, it’s still safe to use emergency pills again.

Why doctors still don’t want you relying on it regularly

Even though it’s safe, there are three big reasons ECPs aren’t recommended as your primary birth control:

  1. Less effective than regular contraception
    • The pill, implant, hormonal IUD and copper IUD are much more effective overall when used properly.
  2. More expensive over time
    • Paying for the morning after pill multiple times can quickly cost more than a subsidised long‑acting reversible contraceptive (LARC) or a PBS‑listed pill.
  3. Unpredictable periods
    • Frequent use can make your cycles harder to track, which can increase anxiety and make it tougher to spot early pregnancy.

If you’re finding you need emergency contraception more than once or twice a year, that’s usually a sign it’s time to upgrade your plan.

We’ve broken down your options – from low‑dose pills to implants and IUDs – in our blog post “Birth Control Options and How to Get Them in Australia”, including how to access online contraception prescriptions safely via telehealth.

At NextClinic, we can:

  • Help you get a pill script online if that’s your preferred method.
  • Talk through LARC options (like implants and IUDs) and provide referrals for insertion.
  • Arrange advance prescriptions or advice around emergency contraception, especially if you know you’re heading into a riskier period (like party season or a new relationship).

Takeaway

You can use the morning after pill more than once. But if you’re needing it regularly, that’s your cue to switch from “emergency back‑up” to a reliable, low‑effort primary method.

Bonus Myth: “Emergency contraception protects against STIs”

Because the morning after pill is taken after sex, it’s easy to assume it’s doing double duty: preventing pregnancy and infections.

The truth: It only prevents pregnancy

Australian state health services are very clear: emergency contraception does not protect you from HIV or other STIs.

That means:

  • If you had unprotected sex with a new or casual partner, you may need both emergency contraception and an STI check.
  • Condoms (internal or external) and other barrier methods are still essential for sexual health protection, even if you’re on the pill, using an implant, or have an IUD.

If you’re unsure about your risk, this is exactly the kind of thing you can talk through in a quick telehealth consultation. We often combine conversations about emergency contraception with STI screening advice, safer sex tips, and longer‑term contraception planning.

So, how safe and effective is emergency contraception really?

Pulling it all together:

  • It’s prevention, not abortion – ECPs and copper IUDs work before a pregnancy is established.
  • It doesn’t cause infertility – fertility returns quickly; there’s no evidence of long‑term damage.
  • You usually have up to 3–5 days, depending on the method, but sooner is always better.
  • Side effects are generally mild and short‑lived, like temporary nausea or cycle changes.
  • Repeat use is medically safe, but not ideal as your main contraception because it’s less effective overall and can make your periods unpredictable.

At the same time, Australian surveys show that:

  • 70% of women feel under‑educated about contraception,
  • 35% have had a pregnancy scare, and
  • 38% have used emergency contraception – often while still unsure what it really does.

That knowledge gap is exactly what keeps myths alive.

Where NextClinic fits in

As an Australian telehealth service, we see first‑hand how stressful it can be to navigate all this in real time – especially if:

  • Your regular GP can’t see you for days.
  • You live regionally and local services are limited.
  • You’re embarrassed or worried about being judged.

We designed our services to make things easier by:

  • Offering fast, discreet telehealth consultations for contraception, including emergency contraception advice.
  • Issuing online prescriptions for regular birth control pills anywhere in Australia, with scripts sent straight to your phone.
  • Providing medical certificates if side effects (from contraception or from EC) knock you around and you need time off work or study.
  • Sharing practical, Aussie‑specific guides on our blog – like “Stay Safe: Your Guide to Contraception This Party Season” – so you’re not relying on US‑centric Plan B advice that doesn’t quite fit our system here.

You should never feel shamed for using emergency contraception. As MSI Australia points out, it’s a responsible way to prevent an unplanned pregnancy – but many women still feel judged or patronised when they seek it.

We’re here to give you straight answers, not side‑eye.

Your challenge for this week

Information is powerful, but it only changes your life if you use it.

This week, choose one practical step to put these reproductive health facts into action:

  • Stock up smartly: If pregnancy is something you want to avoid right now, consider keeping an emergency pill at home just in case – or at least saving the details of a nearby late‑night pharmacy.
  • Upgrade your plan: If you’ve needed the morning after pill in the past year, book a telehealth or in‑person chat about a more reliable contraceptive method that fits your body and lifestyle.
  • Debunk a myth for someone else: If a friend repeats one of these morning after pill myths, gently share what you’ve learned – you never know whose anxiety you might reduce.
  • Check in on STI safety: If you’ve had unprotected sex with a new or casual partner, combine pregnancy prevention with an STI test.
