A pregnancy test after abortion can help you understand your recovery, but the timing of the test matters. Pregnancy hormones may remain in your body for several weeks after an abortion, meaning a standard home pregnancy test can still show a positive result even when the treatment has been successful.

Knowing when to test, how to interpret the result and when to seek medical advice can help you make informed decisions about your aftercare.

The recommended testing schedule depends on the type of abortion, the test provided and the instructions from your healthcare provider. This guide explains what to expect and how to respond to positive, negative or unclear results.

Testing after a medical abortion

If you had a medical abortion using abortion medicines, your provider may supply a low-sensitivity or specially designed pregnancy test to check whether the pregnancy has ended.

For example, BPAS advises patients using its at-home treatment service to take the supplied test three weeks after swallowing the first medication, following the instructions in the treatment pack.

A standard shop-bought pregnancy test is different. Because it can detect lower levels of hCG, it may remain positive for several weeks even when the abortion has been successful.

Testing after a surgical abortion

After a surgical abortion, you may not need routine pregnancy testing if your recovery is uncomplicated. However, your clinic may recommend follow-up testing or further assessment depending on your circumstances.

If you have ongoing pregnancy symptoms, persistent pain or concerns about your recovery, contact your abortion provider for advice.

Why Is a Pregnancy Test Positive After an Abortion?

Pregnancy tests detect hCG, a hormone produced during pregnancy. After an abortion, hCG levels generally decrease, but the hormone does not disappear immediately.

A positive result after treatment can have several explanations.

1. Pregnancy hormones are still present

This is a common reason for a positive home pregnancy test in the weeks following an abortion. According to BPAS, a standard shop-bought test can remain positive for up to six weeks after treatment.

2. The pregnancy may be ongoing

In some cases, an abortion does not end the pregnancy as expected. A positive result on the recommended follow-up test needs to be discussed with your abortion provider.

3. There may be a new pregnancy

Ovulation can return soon after an abortion, sometimes before your next menstrual period. If you have had sex since treatment, a new pregnancy may also need to be considered.

A home pregnancy test cannot always distinguish between these possibilities. Your healthcare provider can advise whether further testing or assessment is necessary.

What Should You Do If Your Pregnancy Test Is Positive?

A positive result can be concerning, but it does not automatically mean that the abortion has failed.

If you have used the special test supplied by your abortion provider and the result is positive, invalid or difficult to interpret, contact the service that provided your treatment.

If you used a standard home pregnancy test, explain when you took it and whether you have experienced any continuing pregnancy symptoms. Your provider can help determine the appropriate next step.

Depending on your situation, further assessment may involve another pregnancy test, blood tests or an ultrasound.

Do not take additional abortion medication based only on a positive pregnancy test. Seek appropriate clinical advice to establish what the result means and whether further care is needed.

What Does a Negative Pregnancy Test Mean After an Abortion?

A negative result on the recommended follow-up test can be reassuring and may indicate that the pregnancy has ended as expected.

However, you should consider the result alongside your symptoms and the instructions provided by your healthcare professional.

If you took a test earlier than recommended, the result may not provide a reliable answer. Ask your provider whether you need to repeat it.

Contact a healthcare professional if you continue to experience pregnancy symptoms or have concerns about whether the abortion was complete, even if your test is negative.

How Long Do Pregnancy Hormones Stay in Your Body?

The time required for hCG levels to decrease varies from person to person.

After an abortion, hCG levels generally fall over time. However, a standard home pregnancy test may continue to detect the hormone for several weeks. BPAS notes that this can sometimes last up to six weeks.

This is why the type of test matters. A low-sensitivity test supplied by an abortion provider may be more appropriate for the recommended follow-up schedule than a highly sensitive shop-bought test.

Repeatedly taking standard pregnancy tests over a short period may not provide a clear answer. Follow your provider’s instructions and ask for medical advice if the result is positive or uncertain.

What Symptoms Should You Monitor After an Abortion?

Pregnancy testing is only one part of post-abortion care. Paying attention to your physical recovery is also important.

Pregnancy symptoms that continue

Symptoms such as nausea, tiredness and breast tenderness often improve after an abortion as hormone levels decrease.

The timing varies, but if you still feel pregnant after about a week, or your symptoms persist or worsen, contact your healthcare provider for advice.

Bleeding and abdominal pain

Bleeding and cramping are common after an abortion, and bleeding may continue for several weeks. However, pain or bleeding that is worsening or not improving should be assessed.

Seek urgent medical advice if you experience severe abdominal pain, fainting, marked dizziness or very heavy bleeding.

Signs of infection

Contact your healthcare provider urgently if you develop a fever, flu-like symptoms, unusual or unpleasant-smelling vaginal discharge, or persistent abdominal tenderness.

In the UK, you can contact NHS 111 for urgent advice. Call 999 or attend an emergency department if you experience a medical emergency.

Can You Get Pregnant Before Your Next Period?

Yes. Fertility can return quickly after an abortion, and ovulation may happen before your next menstrual period.

This means that a new pregnancy is possible before you have another period. If you have had unprotected sex since your abortion and are concerned about becoming pregnant again, ask a healthcare professional about appropriate testing and contraception options.

A positive test in this situation may need further assessment because residual hCG from the previous pregnancy can complicate interpretation.

Your healthcare provider can help determine the appropriate next steps based on the timing of your abortion, any subsequent sexual activity and your symptoms.

Frequently Asked Questions

Can I take a pregnancy test one week after an abortion?

You can take a test, but a standard home pregnancy test may remain positive because hCG is still present. Follow the testing schedule recommended by your abortion provider.

Is it normal to test positive three weeks after a medical abortion?

A positive result needs to be interpreted according to the type of test used. A positive result on a provider-supplied follow-up test should be reported to the provider. A standard home test may remain positive because of residual pregnancy hormones.

How long can a pregnancy test remain positive after an abortion?

A standard shop-bought pregnancy test can remain positive for up to six weeks after an abortion in some cases. The timing varies, so follow your provider’s testing instructions.

Should I repeat a negative pregnancy test?

Follow the instructions supplied with your test. If you tested too early, continue to experience pregnancy symptoms or remain concerned, contact your healthcare provider to determine whether further testing is needed.

When should I contact a healthcare professional?

Seek advice if your follow-up test is positive, invalid or unclear, if you continue to feel pregnant, or if you experience persistent pain, fever or unusual discharge. Severe pain, fainting or very heavy bleeding requires urgent assessment.

Final Thoughts

Taking a pregnancy test after an abortion at the recommended time can help you understand whether the treatment has worked as expected. However, a positive result does not always indicate an ongoing pregnancy because hCG can remain in your body for several weeks.

Use the test recommended by your abortion provider, follow its instructions carefully and seek medical advice if the result is positive, unclear or inconsistent with your symptoms.
