Failed Medication Abortion:
Signs the Abortion Pill Didn’t Work
If you have taken abortion medications and are unsure whether the process worked, it can be difficult to know which symptoms are expected and which may need medical attention. The abortion pill, or medication abortion, generally involves mifepristone followed by misoprostol, which causes the uterus to contract and expel pregnancy tissue through bleeding and cramping. The abortion pill is different from Plan B and other forms of emergency contraception, which work differently and are used for a different purpose.
Understanding what happens during the abortion pill process can help you understand what symptoms are typically expected after taking the medications and which ones may need medical attention. For a broader overview of how medication abortion works, eligibility, screening, risks, and related questions, our Abortion Pill Information Hub brings these topics together in one place.
While medication abortion is effective in most cases, it does not work as expected every time. This article explains possible abortion pill failure symptoms, signs of an incomplete abortion, when medical attention may be needed, and how healthcare professionals can determine whether a pregnancy has ended.
Medical Emergency
The information on this page is for educational purposes and is not a substitute for medical care. If you are experiencing a medical emergency or have symptoms that require immediate attention, call 911 or seek care at the nearest emergency department. Do not delay emergency medical care based on information provided on this website.
What Are the Signs the Abortion Pill May Not Have Worked?
Possible signs that the abortion pill didn’t work may include little or no bleeding after misoprostol, pregnancy symptoms that continue, or a positive pregnancy test at the recommended follow-up time. These signs do not confirm abortion pill failure on their own, but they may be reasons to contact a healthcare professional for further evaluation.
1. Little or No Bleeding After Misoprostol
Bleeding and cramping are expected after taking misoprostol because the medication causes the uterus to contract and empty. If there is no bleeding within 24 hours after taking misoprostol, a healthcare professional should be contacted for further evaluation.
However, the amount of bleeding can vary. Light bleeding after the abortion pill does not necessarily mean the treatment failed, but very little or no bleeding after misoprostol should be discussed with the healthcare professional who prescribed the medication.
2. Pregnancy Symptoms That Continue
Pregnancy symptoms do not always disappear immediately after a medication abortion. However, continuing to feel pregnant about a week later may be a reason for medical follow-up. Symptoms such as ongoing nausea or breast tenderness may raise concern about an ongoing pregnancy after the abortion pill, especially when they do not begin to improve.
3. A Positive Pregnancy Test at Follow-Up
A positive pregnancy test shortly after taking abortion medications does not necessarily mean you are still pregnant after the abortion pill. Pregnancy tests detect human chorionic gonadotropin (hCG), a hormone that can remain in the body for several weeks after a pregnancy ends.
Pregnancy testing may be used as part of follow-up. If a test remains positive at the follow-up time recommended by your healthcare professional, additional evaluation may be needed to determine whether the pregnancy is continuing.
What Are the Signs of an Incomplete Abortion?
An incomplete abortion is different from an ongoing pregnancy. With an incomplete abortion, the pregnancy is no longer developing, but some pregnancy tissue remains in the uterus. With an ongoing pregnancy, the pregnancy continues to develop after the abortion medications were taken.
Possible incomplete abortion symptoms may include:
- Prolonged or irregular bleeding
- Bleeding that does not decrease as expected
- Persistent or worsening cramping
- Ongoing pelvic or abdominal discomfort
However, these symptoms do not necessarily mean an incomplete abortion has occurred. Bleeding and cramping can continue for some time after medication abortion, and experiences can vary from person to person. Prolonged or irregular bleeding can occur when the abortion is incomplete, but medical evaluation is needed to determine whether pregnancy tissue remains.
When Should You Seek Medical Attention After Taking the Abortion Pill?
Bleeding, cramping, nausea, and chills can occur after taking abortion medications. However, some symptoms may point to a complication rather than simply showing that the abortion pill didn’t work. Knowing the difference can help you recognize when medical care may be needed.
1. Heavy Bleeding After the Abortion Pill
Bleeding is expected during a medication abortion, and it may be heavier than a normal period. However, soaking two maxi pads per hour for two hours in a row is considered a reason to contact a healthcare professional promptly.
Heavy bleeding after the abortion pill does not necessarily mean the abortion was successful or unsuccessful. If bleeding is excessive or is accompanied by weakness, dizziness, or fainting, seek medical attention.
2. Severe or Worsening Abdominal Pain
Cramping is common after misoprostol, but severe pain that does not improve, continues to worsen, or feels different from expected cramping should not be ignored.
Sudden severe abdominal or pelvic pain, especially with shoulder pain, weakness, dizziness, or fainting, can also be a sign of an ectopic pregnancy. An ectopic pregnancy develops outside the uterus and requires medical treatment. This is one reason why ultrasound is important before medical abortion.
3. Fever or Signs of Infection
Chills or fever can occur after misoprostol, but a persistent fever or feeling increasingly unwell may be a sign that medical evaluation is needed.
Possible signs of infection after the abortion pill can include:
- Fever above 100.4°F (38°C)
- Chills
- Severe or worsening abdominal or pelvic pain
- Foul-smelling vaginal discharge
- Weakness, fainting, or feeling seriously ill
A fever above 100.4°F that lasts more than four hours, severe lower abdominal pain, chills, a fast heartbeat, or fainting are reasons to contact a healthcare professional or seek emergency care.
If you are experiencing severe symptoms or are unsure whether your symptoms are normal, it is safer to seek medical guidance rather than waiting for them to resolve on their own.
How Is Abortion Pill Failure Confirmed?
Symptoms may raise concern that the abortion pill did not work, but they cannot always confirm whether the pregnancy has ended. A healthcare professional may use pregnancy testing, hCG blood testing, or ultrasound depending on your symptoms and medical situation.
1. Pregnancy Testing
A pregnancy test can determine whether pregnancy hormones are still present. Because hCG does not disappear immediately after a pregnancy ends, a positive result may need to be interpreted alongside the timing of the test and other findings.
If pregnancy hormones remain detectable at follow-up, further evaluation may be recommended.
2. hCG Blood Testing
Blood testing can measure the amount of hCG in the body. Comparing hCG levels over time can help healthcare professionals determine whether the hormone is decreasing as expected after a medication abortion.
Follow-up after medication abortion may include hCG testing when there is uncertainty about whether the pregnancy has ended.
3. Ultrasound
In some situations, ultrasound may be used to determine whether a pregnancy is still developing or whether additional medical evaluation is needed. The appropriate method of confirmation depends on symptoms, pregnancy history, and test results.
What Happens If the Abortion Pill Doesn’t Work?
If the abortion pill doesn’t work, what happens next depends on whether the pregnancy is continuing, the abortion is incomplete, or another medical concern is present.
An ongoing pregnancy may require additional medical treatment or a procedure. An incomplete abortion may be managed with monitoring, medication, or uterine aspiration depending on the individual situation. A healthcare professional should evaluate what has happened before further treatment is considered.
Could a Procedure Be Needed?
In some cases, a surgical procedure may be needed to remove remaining pregnancy tissue or manage an ongoing pregnancy after a failed medical abortion. This is not required in every case, and the decision should be based on a medical evaluation.
If a procedure is being considered, understanding the differences between the abortion pill and surgical abortion can provide additional context about how the two methods differ.
If you suspect the abortion pill did not work, contact a healthcare professional rather than taking additional medication without medical guidance.
How Often Does the Abortion Pill Fail?
Medication abortion may not always successfully end a pregnancy. The chance of abortion pill failure can vary based on factors such as how far along the pregnancy is and the medication regimen used.
Why Does Gestational Age Matter?
The abortion pill tends to be more effective earlier in pregnancy, while the likelihood of an ongoing pregnancy can increase as gestational age advances. Knowing how far along a pregnancy is can help determine whether someone is within the recommended timeframe for medication abortion and what outcomes may be expected.
Gestational age is also one of several factors that can affect eligibility for the abortion pill, along with other medical factors. Pregnancy dating is one of the important pieces of information that may be assessed during pre-abortion screening before abortion medication is taken.
