Ectopic Pregnancy: Key Information

An ectopic pregnancy happens when a fertilised egg implants itself outside the uterus, where it cannot grow properly. In most cases, this occurs in one of the fallopian tubes, which connect the ovaries to the womb. Because the fallopian tubes are not designed to support a growing pregnancy, the egg cannot develop into a baby and may cause serious health risks for the mother if left untreated. This condition requires urgent medical attention to prevent complications.

Early Pregnancy Scans

Signs, symptoms and when to seek help

An ectopic pregnancy occurs when a fertilised egg implants outside the uterus, most commonly in one of the fallopian tubes. This condition is sometimes called a tubal pregnancy and affects approximately 1 in 90 pregnancies in the UK. While the fallopian tubes are the most frequent location, ectopic pregnancies can also occur in the ovary, abdomen, or cervix.

Unfortunately, an ectopic pregnancy cannot result in a viable birth and requires medical attention. Ectopic pregnancies are a medical emergency if untreated, as they can lead to serious complications, including rupture and internal bleeding. Early diagnosis through ultrasound scans and blood tests is critical to managing the condition.

At London Pregnancy Clinic, we recommend early pregnancy scans from six weeks or earlier if you experience symptoms, to help diagnose and manage the situation promptly.

Symptoms of an ectopic pregnancy can include:

  • severe abdominal pain
  • vaginal bleeding
  • discomfort in the shoulder tip, often combined with dizziness or fainting

While it affects around 1 in 90 pregnancies in the UK, early diagnosis and treatment can protect the mother’s health and fertility. Early detection is key to managing the condition safely.

Ectopic Pregnancy Statistics

Prevalence

Around 1 in every 90 pregnancies in the UK is ectopic, affecting approximately 11,000 women annually.

Location

The majority of ectopic pregnancies (over 95%) occur in the fallopian tubes, though they can also develop in the abdomen, ovary, or cervix.

Risk factors

Women with a history of pelvic inflammatory disease (PID), previous ectopic pregnancy, or certain types of fertility treatment, such as IVF, have a higher risk of ectopic pregnancy.

Age factor

The risk of ectopic pregnancy increases with age, particularly in women aged 35-44 years.

Symptoms

Key signs include severe abdominal pain, vaginal bleeding, and shoulder tip pain, often accompanied by dizziness or fainting in severe cases.

Mortality rate

Although rare, ectopic pregnancy can cause life-threatening complications if untreated, though deaths in the UK are now extremely rare.

Fertility impact

After experiencing an ectopic pregnancy, most women go on to have a successful pregnancy, with studies reporting rates of around 56-70% over the following two to three years, though some may face ongoing fertility challenges.

Ectopic Pregnancy – When to come in for a scan?

If you suspect an ectopic pregnancy, timing your scan is crucial. For patients experiencing severe symptoms such as intense abdominal pain, heavy bleeding, or fainting, the first point of contact should always be A&E or an early pregnancy unit. These symptoms may indicate a medical emergency.

However, if your symptoms are milder—such as light bleeding, brown discharge, or mild pain—and you are under six weeks pregnant, it may be appropriate to book an early pregnancy scan for reassurance. Although six weeks is typically the recommended time for the first scan, coming in earlier can help monitor your pregnancy and check for signs of potential complications.

When to come in for a scan

It’s important to note that diagnosing an ectopic pregnancy can be challenging, due to the small size of the embryo before 6 weeks. In some cases, you may be asked to return for a follow-up scan to confirm the findings as your pregnancy progresses.

An early scan is an assessment and reassurance tool rather than a definitive diagnostic test: a normal early scan cannot always confirm or exclude an ectopic pregnancy, and diagnosis may require repeat scans and blood tests.

Early scans at London Pregnancy Clinic provide expert assessment and peace of mind, but always prioritise your safety by seeking emergency care when necessary.

Your questions answered

What is an ectopic pregnancy?

An ectopic pregnancy occurs when a fertilised egg implants outside the uterus, most commonly in one of the fallopian tubes. This condition is sometimes called a tubal pregnancy and affects approximately 1 in 90 pregnancies in the UK. While the fallopian tubes are the most frequent location, ectopic pregnancies can also occur in the ovary, abdomen, or cervix. Unfortunately, an ectopic pregnancy cannot result in a viable birth and requires medical attention.

Ectopic pregnancies are a medical emergency if untreated, as they can lead to serious complications, including rupture and internal bleeding. Early diagnosis through ultrasound scans and blood tests is critical to managing the condition. At London Pregnancy Clinic, we recommend early pregnancy scans from six weeks or earlier if you experience symptoms, to help diagnose and manage the situation promptly.

What are the symptoms of an ectopic pregnancy?

The symptoms of an ectopic pregnancy can vary, but early signs often include abnormal vaginal bleeding, light spotting, or brown discharge. You might also experience lower abdominal pain, often localised to one side. Other symptoms can include shoulder tip pain, which is sometimes a sign of internal bleeding, or dizziness and fainting in severe cases.

Many symptoms can overlap with normal early pregnancy discomfort or miscarriage, so it is vital to get an expert assessment if you’re concerned. If symptoms are severe, such as sharp abdominal pain or heavy bleeding, you should immediately go to A&E. For milder symptoms like light bleeding or discomfort, an early pregnancy scan at London Pregnancy Clinic can help determine the cause and provide reassurance.

How is an ectopic pregnancy diagnosed?

Ectopic pregnancies are typically diagnosed using a combination of ultrasound scans and blood tests. A transvaginal ultrasound (a small internal scan probe that gives the clearest early view) is the most effective way to visualise the uterus, fallopian tubes, and ovaries to determine where the pregnancy has implanted. If the ultrasound is inconclusive, repeated scans may be necessary as the pregnancy progresses.

Blood tests measuring hCG (human chorionic gonadotropin) levels can also help diagnose ectopic pregnancies. In a normal pregnancy, hCG levels roughly double every 48 hours, but in an ectopic pregnancy, the rise may be slower or level off (plateau). If you suspect an ectopic pregnancy, consulting with experienced fetal medicine specialists, like those at London Pregnancy Clinic, ensures a thorough and accurate assessment.

What causes an ectopic pregnancy?

An ectopic pregnancy occurs when the fertilised egg is unable to travel to the uterus due to blockage or damage to the fallopian tubes. Common causes include pelvic inflammatory disease (PID), previous ectopic pregnancies, or surgeries on the fallopian tubes. Other risk factors include smoking, endometriosis (a condition where womb-like tissue grows outside the womb), and the use of fertility treatments like IVF.

However, many women with ectopic pregnancies have no identifiable risk factors. Understanding your medical history and undergoing early scans can help detect potential issues early. At London Pregnancy Clinic, we recommend discussing your health background during your appointment to help identify any possible risks.

What are the treatment options for an ectopic pregnancy?

Treatment for an ectopic pregnancy depends on how far the pregnancy has progressed and your symptoms. Medical treatment often involves an injection of a medicine called methotrexate to stop the growth of the pregnancy tissue. This option is generally used if the ectopic pregnancy is diagnosed early, and there is no immediate risk of rupture.

If the ectopic pregnancy has progressed or ruptured, surgical intervention may be necessary. This typically involves a laparoscopy (keyhole surgery) to remove the ectopic tissue or, in some cases, the affected fallopian tube. Early diagnosis at clinics like London Pregnancy Clinic can improve the chances of non-surgical management and preserve fertility.

Can an ectopic pregnancy affect future fertility?

An ectopic pregnancy can impact future fertility, particularly if one of the fallopian tubes is damaged or removed. However, many women go on to have successful pregnancies after treatment. If one fallopian tube remains healthy, the chances of natural conception are still good.

To reduce the risk of future ectopic pregnancies, addressing underlying conditions such as pelvic inflammatory disease or endometriosis is essential. At London Pregnancy Clinic, we offer preconception care and fertility assessments to help you plan for a healthy pregnancy after an ectopic pregnancy.

What should I do if I suspect an ectopic pregnancy?

If you suspect an ectopic pregnancy, the severity of your symptoms will determine your course of action. For severe symptoms like sharp pain or heavy bleeding, go to A&E immediately, as this may indicate a ruptured ectopic pregnancy. For milder symptoms like spotting or mild discomfort, book an early pregnancy scan as soon as possible.

At London Pregnancy Clinic, we offer early scans to assess your pregnancy and identify potential issues like ectopic pregnancies. Our specialists provide a thorough evaluation, ensuring you receive the care and support you need during this critical time.

When is the best time to detect an ectopic pregnancy?

Ectopic pregnancies are most commonly detected between six to eight weeks of pregnancy, as this is when the embryo becomes large enough to be seen on an ultrasound. However, if you experience symptoms such as light bleeding or pain earlier than this, it’s advisable to seek an early scan for reassurance.

Diagnosing an ectopic pregnancy before six weeks can be challenging due to the embryo’s small size. This may require follow-up scans or additional blood tests to monitor your hCG levels. At London Pregnancy Clinic, our advanced ultrasound equipment and experienced specialists ensure the most accurate assessment possible.

Can ectopic pregnancies resolve on their own?

In rare cases, an ectopic pregnancy may resolve without treatment, particularly if it is identified very early and the body reabsorbs the pregnancy tissue. This is known as a “resolving ectopic pregnancy.” However, these cases are uncommon, and most ectopic pregnancies require medical or surgical management to prevent complications.

Leaving an ectopic pregnancy untreated can lead to serious risks, including rupture and internal bleeding. If you suspect an ectopic pregnancy, early evaluation by specialists at London Pregnancy Clinic can help determine the appropriate course of action to protect your health.

How can I reduce my risk of an ectopic pregnancy?

While not all ectopic pregnancies can be prevented, certain steps can help reduce your risk. Treating conditions like pelvic inflammatory disease, stopping smoking, and maintaining overall reproductive health are essential. Regular check-ups and addressing any fertility concerns can also help.

If you have a history of ectopic pregnancies or other risk factors, pre-pregnancy counselling and early scans can be invaluable. London Pregnancy Clinic offers expert advice and early pregnancy assessments to help you minimise risks and feel confident in your pregnancy journey.
