Using “the abortion pill” — or, to be more accurate, abortion pills — is a safe and reliable way to end a pregnancy up to about 12 weeks after the first day of your last period.

You can usually carry out all or part of the procedure at home, which can be more comfortable for some people.

But that can naturally make you wonder about whether it has worked.

Although a follow-up appointment is the best way to get reassurance, there are a number of signs that may let you know the medication has been successful.

In many cases, “the abortion pill” is actually two separate medications — mifepristone and misoprostol — taken in two separate doses.

Cramping and bleeding within a few hours of taking the second medication, misoprostol, is a good indicator that the procedure has worked.

Bleeding or passing large blood clots generally shows that the embryonic or fetal tissue (likely to be white or gray) is exiting your body. Cramping helps your uterus return to its usual state.

The process usually takes 2–3 days to complete. You may experience symptoms for a few weeks after taking all the medications.

If you’re using telemedicine or seeing a healthcare professional in person to have a medication abortion, you’ll have an appointment with a nurse or doctor who will ask about your medical history and explain how the process works.

If you’re seeing a healthcare professional in person and haven’t had a recent ultrasound, they will likely perform one to see how far along the pregnancy is.

At this appointment, the healthcare staff will give you the first medication, mifepristone. In many cases, they will ask you to take it there and then.

The second medication, misoprostol, can be taken 24–48 hours after the first one.

You’ll be given a slowly dissolving tablet that you can place in your vagina, under your tongue, or between your teeth and cheek. A healthcare professional will advise you on the best way to take this medication.

Some people return to a medical office to take misoprostol, while others take it at home.

According to Planned Parenthood, bleeding and cramping will typically start within 4 hours. Contact a healthcare professional if you don’t experience any bleeding within 24 hours.

In most cases, you’ll pass the pregnancy within 4–6 hours, though it can take a bit longer. You may also experience lighter bleeding and cramping for a few weeks afterward.

A follow-up appointment with a healthcare professional, if necessary, usually takes place around 2 weeks after you’ve taken all medication.

A medication abortion generally uses two different medications to end a pregnancy.

The first medication, mifepristone, blocks an important pregnancy hormone called progesterone. This results in the breakdown of the uterine lining and stops the growth of the embryo or fetus.

Your body soon realizes that the pregnancy can’t continue, so the second medication, misoprostol, helps push out the tissue through your vagina.

Your body does this by causing your uterus to contract, which leads to a similar level of cramping and bleeding as you would experience during a miscarriage.

The medication used to complete abortion is highly effective, but its effectiveness does decrease the further along the pregnancy is.

According to Planned Parenthood, the medication works for 94–98% of people who are 8 or fewer weeks pregnant.

The effectiveness decreases to 91–93% in people who are 9–10 weeks pregnant.

The authors of a 2011 research review found no evidence of a difference between the effectiveness of medical abortions and surgical procedures. A 2015 study also found that both options were highly effective in the first trimester.

According to the University of California – San Francisco, 3–5% of people need a surgical abortion after a medication abortion.

Certain factors can affect the medication’s effectiveness.

For example, a medication abortion won’t work if you have an ectopic pregnancy or if you don’t take all the medications correctly.

Additionally, you should not have a medication abortion if you have an IUD or certain medical conditions, such as a bleeding disorder.

Healthcare staff can check for all of the above and provide clear instructions before dispensing abortion medication.

People often liken the feeling of medication abortion to an early miscarriage.

After taking the second medication, you’ll likely experience abdominal cramps and heavy bleeding for a few hours.

Depending on how far along the pregnancy is, you may pass larger tissues that are brown or red, and you may be able to see the white pregnancy sac.

Misoprostol can also cause:

  • vomiting
  • diarrhea
  • headaches
  • tiredness
  • fever-like symptoms

Try to look after yourself by staying in a comfortable place, whether that’s your home or the home of family or friends.

If you can, take a couple of days off from work or other duties so you can rest.

Lying down with a hot water bottle on your abdomen can help relieve any pain. You may even find sitting on the toilet to be a more comfortable position.

You’ll also need highly absorbent menstrual pads for the bleeding.

If you need pain medication, avoid aspirin, which can worsen bleeding. Instead, take ibuprofen (Advil, Motrin). You may find it helpful to take pain medication around 30 minutes before the misoprostol.

If you feel that something isn’t right — especially if you’re soaking two or more pads per hour for a few hours or have a fever that lasts longer than a day — seek medical advice.

Hospital or clinic staff don’t need to know that you’ve taken the abortion pill if you feel unsafe telling them. Your symptoms will mimic those of a natural miscarriage, so staff won’t be able to tell the difference.

As soon as the pregnancy has ended, your symptoms should begin to reduce.

Bleeding may be lighter, and cramping may not feel as severe. Other side effects, such as fever or nausea, should also disappear.

But it may take a couple of days for you to get back into your usual routine, as the process can make you tired.

It’s common to experience lighter bleeding for a few weeks after taking medication used for abortion, so don’t worry if you’re still spotting after your follow-up appointment.

Before your follow-up appointment, try to keep track of how much you’re bleeding. Be sure to contact a healthcare professional if you have any concerns.

Around 4–6 weeks after your abortion, your period should return.

Be aware that your body can start to ovulate around 3 weeks after you take the medication, and some people ovulate as soon as 8 days afterward — meaning you can become pregnant again pretty quickly.

If you have a follow-up appointment planned, it may take place over the phone or in person, depending on your and your doctor’s preferences.

Your doctor will use this appointment to determine whether your body is healing properly. They’ll also look for any signs of infection.

During this appointment, they’ll ask you about the process, including:

  • how much bleeding you’ve experienced
  • whether you’re still bleeding
  • whether you’ve seen evidence that the gestational sac or embryo has left your body

At an in-person appointment, they may also physically check your cervix and uterus, perform lab tests to check for the pregnancy hormone, and carry out an ultrasound to determine whether the medication worked.

If you opt for a telemedicine appointment, they’ll likely advise you to take a pregnancy test at home.

Try to avoid taking an at-home test too soon after an abortion, as the pregnancy hormone may linger in your body. It’s best to wait 2–4 weeks to avoid a false-positive result.

Although a medication abortion is effective in the vast majority of cases, there’s a small chance that it may not work.

A doctor or other healthcare professional will be able to determine this at a follow-up appointment.

If you’re still pregnant, a healthcare professional can discuss other abortion options with you.

You may be able to take another dose of one or both abortion medications, or you may need a surgical abortion instead.

How long do the side effects of misoprostol last?

A medication abortion with mifepristone and misoprostol typically takes 2–3 days to complete. You may experience symptoms for a few weeks after taking both medications.

How long does it take for misoprostol to soften the cervix?

Misoprostol, the second medication in a medication abortion, typically begins to produce bleeding and cramping within 24 hours of when you take the pill.

What does misoprostol do to the uterus?

Misoprostol helps push out the tissue through your vagina by making your uterus contract. This typically leads to a level of cramping and bleeding similar to what would you experience during a miscarriage.
