When you’re facing an unplanned pregnancy, it can feel like everyone has an opinion and almost no one has straight answers. Two terms you’ve likely come across, Plan B and the abortion pill, are frequently used interchangeably, but they are not the same thing, and the difference matters.
You deserve accurate information without pressure or judgment. Find care nearby for pregnancy testing, ultrasounds, and other services to understand your situation and think through your options clearly.
Plan B: Preventing Pregnancy
Plan B, commonly called the morning-after pill, contains levonorgestrel, a synthetic hormone that works primarily by delaying ovulation to reduce the chance of fertilization when taken within 72 hours of unprotected sex.
Though it was once thought that Plan B might prevent a fertilized egg from implanting in the uterus, the FDA now states there is not sufficient evidence to support this, and the drug does not end an existing pregnancy. This update was reflected in the Plan B drug label as of December 2022.
Plan B is available over the counter without a prescription, but it does affect your hormones. Potential side effects include tiredness, nausea or vomiting, breast tenderness, headache, dizziness, cramping or lower abdominal pain, and irregular or heavier bleeding.
The Abortion Pill: Ending an Existing Pregnancy
Also called a medical abortion, the abortion pill is a multi-step process that uses two different drugs. The first drug, mifepristone, blocks progesterone, a hormone needed to sustain a pregnancy. The second drug, misoprostol, is taken 1 to 2 days later and causes the uterus to contract and vaginal bleeding, expelling the pregnancy. The abortion pill is FDA-approved only through 10 weeks of gestation.
Unlike Plan B, the abortion pill cannot prevent pregnancy from occurring.
The abortion pill carries health risks, including heavy vaginal bleeding, incomplete abortion, and infection, and requires oversight from a licensed provider. Because of these considerations, it is a very different approach from emergency contraception and is only relevant after a pregnancy has been confirmed.
Why This Difference Matters
The key distinction is timing and purpose: Plan B prevents pregnancy before it starts, while the abortion pill ends an existing pregnancy. They are not interchangeable, and understanding which situation applies to you is an important first step.
That starts with a pregnancy test. If your test is positive, confirming the pregnancy with an ultrasound can tell you how far along you are, where the pregnancy is located, and whether the pregnancy appears to be developing with cardiac activity, all of which can shape your steps and options.
