Ectopic Pregnancy: Early Symptoms, Causes, Diagnosis and Treatment Options

Published on 28 Oct 2026

A positive pregnancy test usually brings joy, but sometimes it is followed by pain on one side or unexpected spotting. One of the conditions doctors check for at this stage is ectopic pregnancy - a pregnancy that has implanted outside the womb. It is not common, but it is important to recognise early, because early diagnosis keeps more treatment choices open and protects your health.

This guide explains, in plain language, what an ectopic pregnancy is, the early symptoms, why it happens, how it is diagnosed with blood tests and a scan, and what treatment involves. It also covers what it means for a future pregnancy, which is often the first question couples in Visakhapatnam ask.

Quick answer: An ectopic pregnancy is a pregnancy that grows outside the womb, most often in a fallopian tube. It cannot continue safely and cannot be moved into the womb. Typical symptoms appear between weeks 4 and 12 and include one-sided lower tummy pain, spotting and shoulder tip pain. It is diagnosed with a transvaginal scan and beta hCG blood tests, and treated with monitoring, medicine (methotrexate) or keyhole surgery.

Ectopic pregnancy explained: what happens and why it matters

After fertilisation, the embryo normally travels down the fallopian tube and implants in the lining of the womb. In an ectopic pregnancy, it implants somewhere else. According to the NHS, most ectopic pregnancies are in a fallopian tube, which is why you may also hear the term tubal pregnancy. Rarely, it can implant in an ovary, the cervix, a caesarean scar or inside the abdomen.

A fallopian tube is narrow and cannot stretch like the womb. As the pregnancy grows, it can cause pain and bleeding and, if it is not treated, the tube can burst (rupture). The NHS notes that around 1 in 90 pregnancies in the UK is ectopic. Comparable national figures for India are not routinely published, but the condition is seen in every early pregnancy service.

Important to know

  • An ectopic pregnancy cannot be saved or moved into the womb with current medical techniques.
  • It is not caused by anything you did, such as lifting, travel, sex or food.
  • A positive home test does not rule it out - the test is positive in an ectopic pregnancy too.

Early symptoms of ectopic pregnancy

Some women have no symptoms at all and the ectopic pregnancy is found on an early scan. When symptoms do appear, the NHS says they tend to start between the 4th and 12th week of pregnancy. They often look like other, harmless early pregnancy changes, which is why a scan and blood tests matter.

  • A missed period and other signs of early pregnancy.
  • Pain low down in the tummy, usually on one side, which may be mild or sharp.
  • Vaginal bleeding or a brown, watery discharge, often lighter than a period.
  • Pain in the tip of the shoulder, where the shoulder ends and the arm begins.
  • Discomfort when passing urine or stool.

These symptoms do not always mean an ectopic pregnancy - a urine infection, a stomach upset or a threatened miscarriage can cause similar pain. The point is not to guess at home but to get checked if you might be pregnant and notice any of them, even before you have taken a pregnancy test.

When it is an emergency

The NHS advises going to the nearest emergency department straight away if you have a combination of sudden, sharp, severe tummy pain, feeling very dizzy or fainting, feeling sick, or looking very pale. These can be signs that a tube has ruptured and internal bleeding has started. A rupture is uncommon and treatable when it is dealt with quickly, so do not wait for the pain to settle or for a routine appointment.

Causes and risk factors

In many women there is no clear reason. Anything that damages or narrows a fallopian tube can slow the embryo down, so it implants before reaching the womb. ACOG and the NHS list these factors as raising the chance of an ectopic pregnancy:

  • A previous ectopic pregnancy.
  • Previous surgery on the fallopian tubes, including sterilisation or its reversal.
  • Pelvic inflammatory disease (PID) or past sexually transmitted infections such as chlamydia.
  • Endometriosis or previous abdominal surgery that left scar tissue.
  • Smoking.
  • Being over 35.
  • Fertility treatment, including IVF.
  • Becoming pregnant with an intrauterine device (IUD) or after the morning-after pill - pregnancy is rare with these, but when it happens it is more likely to be ectopic.

Having a risk factor does not mean you will have an ectopic pregnancy. It means an early scan is sensible once your test is positive, so your doctor can confirm where the pregnancy is.

Can ectopic pregnancy happen after IVF?

Yes. Even though embryos are placed directly in the womb during IVF, they can move into a tube before implanting. The chance is small, but it is one reason fertility teams arrange a beta hCG blood test and an early scan after a positive result. Our team describes this follow-up - beta hCG and early pregnancy monitoring - on the fertility services page at padmasrihospitalsandivfcentre.com/fertility-services/.

How is ectopic pregnancy diagnosed?

Diagnosis is based on your symptoms, an examination and two key tests. NICE guidance recommends a transvaginal ultrasound (a scan using a slim probe placed in the vagina) as the main test to locate a pregnancy, because it gives a much clearer picture in early weeks than a scan over the tummy.

A beta hCG blood test measures the pregnancy hormone. A single value cannot tell where the pregnancy is, so the test is usually repeated about 48 hours later. In a healthy pregnancy inside the womb, hCG normally rises steadily; in an ectopic pregnancy it often rises more slowly, plateaus or falls. Your doctor reads the trend together with the scan, not a single number.

Sometimes the test is positive but nothing is seen on the scan, either inside or outside the womb. This is called a pregnancy of unknown location. It may be a very early normal pregnancy, a miscarriage or an ectopic pregnancy, and doctors repeat the blood tests and scan until the picture is clear. This waiting period is hard emotionally, so ask your team to explain each result.

Key points so far

  • Most ectopic pregnancies are in a fallopian tube.
  • Symptoms usually appear between weeks 4 and 12, but some women have none.
  • A transvaginal scan plus repeated beta hCG tests confirm the diagnosis.
  • Sudden severe pain, fainting or paleness needs emergency care.

Treatment options

The right option depends on your symptoms, the size and location of the pregnancy, your hCG level and whether there is internal bleeding. NICE and the NHS describe three main approaches:

  1. Expectant management (watch and wait): if hCG is low and falling and you are well, the pregnancy may resolve on its own. You will need blood tests until hCG returns to negative.
  2. Medicine (methotrexate): an injection that stops the pregnancy from growing; the body then absorbs it. It suits women who are stable, with no significant pain, and an hCG level within a range set by your doctor. Follow-up blood tests continue for a few weeks, and the NHS advises waiting at least 3 months after methotrexate before trying to conceive.
  3. Surgery: usually done by laparoscopy (keyhole surgery) through small cuts in the tummy. The surgeon removes the pregnancy and, depending on the condition of the tube, either removes the affected tube (salpingectomy) or opens it to remove the pregnancy (salpingostomy). Surgery is needed if a tube has ruptured or the pregnancy is larger.

Medicines for ending a pregnancy that are sold over the counter do not treat an ectopic pregnancy, and taking them without a confirmed diagnosis can delay proper care. Only a doctor who has seen your scan and blood results can decide which treatment is safe for you. At Padmasri, laparoscopic surgery for ectopic pregnancy is part of the gynaecology services listed at padmasrihospitalsandivfcentre.com/gynecology/.

Recovery and emotional care

Physical recovery after keyhole surgery is usually a few weeks, and after methotrexate you may feel tired or have some tummy discomfort for a while. Many women and their partners also feel grief, anxiety or guilt after losing a pregnancy, even a very early one. These feelings are normal. Talking to your doctor, your partner or a counsellor helps, and it is fine to take time before thinking about trying again.

Fertility and future pregnancy

Most women who have had an ectopic pregnancy can become pregnant again, including women who have had one tube removed, because the remaining tube still works. The chance of another ectopic pregnancy is higher than average, so in your next pregnancy your doctor will usually suggest an early scan around 6 to 8 weeks to confirm it is in the womb. If both tubes are damaged or removed, IVF is an option that bypasses the tubes; you can read about it at padmasrihospitalsandivfcentre.com/in-vitro-fertilization.php.

Lowering the risk where possible

Not every ectopic pregnancy can be prevented, but some risks can be reduced. Stopping smoking, using condoms to lower the chance of sexually transmitted infections, getting pelvic infections treated promptly, and having an early scan if you have had an ectopic pregnancy or tubal surgery before all help. Routine pregnancy care and early scans are part of the obstetric care described at padmasrihospitalsandivfcentre.com/gynecology-obstetrics.php.

Frequently asked questions

Can an ectopic pregnancy be saved?

No. With current medical techniques an ectopic pregnancy cannot be moved into the womb or continue safely. Treatment focuses on protecting your health and, where possible, your fallopian tubes for future pregnancies.

Will a pregnancy test be positive in an ectopic pregnancy?

Yes. Home urine tests and blood hCG tests are usually positive. They confirm pregnancy but cannot show where it is, which is why a transvaginal scan and repeated beta hCG tests are needed.

At which week do ectopic pregnancy symptoms start?

According to the NHS, symptoms usually develop between the 4th and 12th week of pregnancy. Some women have no symptoms and the ectopic pregnancy is found on an early scan.

Can an ectopic pregnancy be seen on ultrasound?

Often yes, on a transvaginal scan. Very early on it may not be visible yet; this is called a pregnancy of unknown location, and the scan and blood tests are repeated until the location is clear.

Can an ectopic pregnancy be treated without surgery?

In selected cases, yes. If you are stable and hCG levels are within the range your doctor sets, monitoring or methotrexate medicine may be used. Surgery is needed if a tube has ruptured or the pregnancy is larger.

Can I get pregnant normally after an ectopic pregnancy?

Most women can, even with one tube. Your doctor will usually suggest an early scan in your next pregnancy, and after methotrexate the NHS advises waiting at least 3 months before trying to conceive.
