How Emergency Contraception Works

Accidents happen, even when you’re careful. Whether a condom broke, you missed your pill, or had unprotected sex, emergency contraception offers a safe, effective backup option to prevent pregnancy. But how does it work, when should you take it, and what should you expect?

If you’re exploring birth control options in general, you might want to check out our full guide on Choosing the Right Contraceptive Method to understand all your choices better.

What Is Emergency Contraception?

Emergency contraception refers to methods used to prevent pregnancy after unprotected sex or contraceptive failure. It’s not the same as an abortion pill, it prevents pregnancy before it happens, not after.

There are two main types:

  1. Emergency contraceptive pills (ECPs) – Often called the “morning-after pill”
  2. Copper IUD (Intrauterine Device) – The most effective option if inserted within 5 days

Types of Emergency Contraceptive Pills

1. Levonorgestrel Pill

Brand examples: i-Pill, Plan B One-Step

  • Best taken within 72 hours (3 days)
  • Available over the counter in many countries
  • Effectiveness decreases with time

2. Ulipristal Acetate Pill (Ella)

  • Prescription-only in most places
  • Effective up to 5 days after intercourse
  • More effective than levonorgestrel, especially for people over 70 kg

How Does Emergency Contraception Work?

Emergency contraception works primarily by:

  • Delaying ovulation (so there’s no egg to fertilize)
  • Altering the uterine lining, preventing implantation
  • Thickening cervical mucus, making it harder for sperm to reach the egg

It does not terminate an existing pregnancy. If you’re already pregnant, emergency contraception won’t be effective.

When Should You Take It?

Timing is crucial. The sooner you take emergency contraception, the better. Here’s a simple window:

  • Levonorgestrel: Within 72 hours (best within 24)
  • Ulipristal Acetate: Up to 120 hours (5 days)
  • Copper IUD: Within 5 days (120 hours)

Pros of Emergency Contraception

  • Effective at preventing unintended pregnancy
  • Non-invasive and quick to take
  • Available without prescription (in many places)
  • No long-term effects on fertility
  • Can be a lifesaver in cases of contraceptive failure

Possible Side Effects

Most side effects are temporary and mild:

  • Nausea or vomiting
  • Headache
  • Breast tenderness
  • Dizziness
  • Slight delay or early start of your next period

If you vomit within two hours of taking the pill, you may need to take another dose.

Common Myths About Emergency Contraception

Myth 1: It causes abortion
Truth: It prevents pregnancy before it begins.

Myth 2: It can’t be used more than once
Truth: It’s safe for occasional use but should not replace regular birth control.

Myth 3: It affects future fertility
Truth: There is no evidence that emergency contraception impacts long-term fertility.

Who Should Use Emergency Contraception?

  • Condom slipped or broke
  • Missed 2 or more birth control pills
  • Had unprotected sex
  • Forgot to apply your contraceptive patch or insert ring
  • Experienced forced sex or assault

It’s also a good option if you miscalculated ovulation days while using fertility awareness. Read more on tracking ovulation naturally.

When to See a Doctor

  • If your period is more than 7 days late
  • If you experience unusual bleeding or severe pain or If you have vomiting after taking the pill
  • To discuss switching to a regular contraceptive method

Also, if you’re concerned about STI exposure, speak to your healthcare provider immediately.

Emergency Contraception for Athletes

Athletes often prefer low-hormone or non-hormonal methods. Emergency contraception is safe for them too, especially those who avoid daily hormonal intake. It’s a good occasional fallback without long-term hormone exposure.

However, if you experience discomfort during workouts or training, conditions like vulvodynia might require attention.
