# Plan B vs. Plan C: What's the Difference?

[Abortion Pill](https://chariscenter.org/helpful-advice/tag/abortion-pill)

![Plan B vs. Plan C: What's the Difference?](https://chariscenter.org/hubfs/Imported_Blog_Media/Empowering%20Healthcare%20Consultation%20with%20Pregnancy%20Test%20and%20Ultrasound.png)

**Plan B. Plan C. The abortion pill.**

If you're worried about an unexpected pregnancy, all the names can get confusing fast. But Plan B and Plan C are **two very different medications used at different points.**

Here's the simplest difference:

- **Plan B is emergency contraception intended to help prevent pregnancy.**
- **Plan C is a term commonly used for medication intended to end an existing pregnancy.**

> Have questions about abortion or early pregnancy? **[Text with our nurses anytime at (580) 441-5611](sms:+15804415611).**

 

## What Is Plan B?

**Plan B is emergency contraception.** It's intended to reduce the chance of pregnancy after unprotected sex or contraceptive failure, such as a broken condom.

Plan B contains **levonorgestrel**, which primarily works by delaying or preventing ovulation.

**Plan B does not end an existing pregnancy and is not the abortion pill.**

Timing matters. Plan B is labeled for use within **72 hours (3 days)** after unprotected sex and works best when taken as soon as possible. As more time passes, Plan B becomes less effective.

 

## What Is Plan C?

**Plan C** is a term commonly used for medication abortion, **also known as the abortion pill.**

Unlike Plan B, Plan C is intended to end an existing pregnancy. Medication abortion typically involves two medications:

- **Mifepristone**, which blocks progesterone, a hormone needed for a pregnancy to continue.
- **Misoprostol**, which causes the uterus to contract and empty.

So while the names sound similar, **Plan B helps prevent pregnancy while Plan C ends an existing pregnancy.**

 

## Which One Applies to Me?

**Timing makes a big difference.**

If unprotected sex happened within the last **3 days**, Plan B may still be an option.

If **your period is late, you've had a positive pregnancy test, or you think you may already be pregnant**, Plan B will not end an existing pregnancy.

That's when confirming whether you're pregnant can help you understand what comes next.

Charis Center offers [**free pregnancy testing in Duncan, OK**](https://chariscenter.org/pregnancy-tests), so you can get an answer without relying on symptoms or timing alone.

 

## Considering Plan C?

If your pregnancy test is positive and you're considering Plan C or the abortion pill, **there's more you should learn about your specific pregnancy first.**

You'll want answers to questions like:

- **How far along am I?**
- **Where is the pregnancy developing?**
- **What abortion information applies to my pregnancy?**

These details matter because timing can affect what abortion information may apply to your pregnancy.

The abortion pill also **does not treat an ectopic pregnancy**, which develops outside the uterus and can become a medical emergency.

 

> Charis Center offers a [**free Pre-Abortion Screening**](https://chariscenter.org/abortionscreening) designed specifically for those considering or planning for abortion. Get free pregnancy testing, ultrasound & personalized abortion information before moving forward.
