An ectopic pregnancy occurs when a fertilised egg implants outside the uterus instead of inside the uterine cavity. In most cases it develops in a fallopian tube, which is why it is sometimes called a tubal pregnancy.
An ectopic pregnancy cannot continue as a normal pregnancy, and it can become a medical emergency if the tube ruptures and causes internal bleeding. Recognising the early symptoms and getting prompt care can protect your health and, in many cases, your future fertility.
What Are the Symptoms of Ectopic Pregnancy?
Symptoms vary from person to person. Some women have none in the early stages, while others notice them soon after a missed period.
1. Abdominal or Pelvic Pain
Pain in the lower abdomen or pelvis is one of the most common symptoms. It is often felt on one side and can range from mild to severe. It may come and go at first, then become constant or more intense.
2. Vaginal Bleeding or Spotting
Unusual bleeding or spotting in early pregnancy is a warning sign. It can look different from a normal period, such as lighter, darker, brownish or watery. Any bleeding during pregnancy, especially with pain, should be checked by a doctor.
3. Shoulder Tip Pain
Internal bleeding can irritate the diaphragm and cause pain at the tip of the shoulder. Not everyone with an ectopic pregnancy has this symptom, but it is an important warning sign, particularly with abdominal pain or dizziness.
4. Dizziness, Weakness or Fainting
Feeling faint, light-headed, or unusually weak can indicate significant internal bleeding and needs immediate medical attention.
5. Pain or Pressure During Bowel Movements or Urination
Some women feel discomfort or pressure when passing stools or urine, often along with pelvic pain.
6. Usual Early Pregnancy Symptoms
An ectopic pregnancy can start like a normal one, with a missed period, nausea, breast tenderness, fatigue and a positive pregnancy test. Because of this, a scan is needed to confirm the pregnancyis location.
When Do Ectopic Pregnancy Symptoms Start?
Symptoms commonly appear between 4 and 12 weeks of pregnancy, but timing varies. Some ectopic pregnancies are found before any symptoms appear, during an early pregnancy scan.
Emergency room or appointment?
| Go to the emergency room now | Book an appointment soon |
|---|---|
| Severe or sudden abdominal pain | Positive pregnancy test with mild pain or spotting |
| Shoulder tip pain | Light bleeding without severe pain |
| Fainting, dizziness, rapid heartbeat | Previous ectopic pregnancy and a new positive test |
| Heavy bleeding | Uncertainty about where the pregnancy is located |
If in doubt, get checked the same day.
What Causes an Ectopic Pregnancy?
It happens when the fertilised egg cannot travel normally through the fallopian tube to the uterus. Factors that may raise the risk include:
- A previous ectopic pregnancy
- Previous surgery on the fallopian tubes or pelvis
- Pelvic inflammatory disease (PID) or infections such as chlamydia
- Conditions affecting the fallopian tubes, such as endometriosis
- Certain fertility treatments, including IVF
- Pregnancy with an intrauterine device (IUD) in place, although pregnancy with an IUD is uncommon
- Smoking
Having a risk factor does not mean you will have an ectopic pregnancy, and many women with an ectopic pregnancy have no known risk factors.
How Is Ectopic Pregnancy Diagnosed?
Pregnancy test: confirms pregnancy but not its location.
Blood test (hCG): doctors measure the pregnancy hormone human chorionic gonadotropin (hCG) and often repeat the test after 48 hours to see how the level changes.
Transvaginal ultrasound: the main test to check whether the pregnancy is inside the uterus and to look for signs of an ectopic pregnancy.
Sometimes the pregnancy cannot be seen right away (called a “pregnancy of unknown location”), and repeated blood tests and scans are needed over a few days.
How Is Ectopic Pregnancy Treated?
Treatment depends on the location and size of the pregnancy, hCG levels, your symptoms, whether there is internal bleeding, and your overall health.
Expectant Management
In carefully selected cases where hCG is low and falling, and you have no significant symptoms, doctors may monitor you closely without immediate treatment.
Medical Treatment
Methotrexate is a medicine that stops the pregnancy from growing. It suits selected patients who are stable and whose hCG is within a suitable range. It requires follow-up blood tests until hCG returns to normal, and you will be advised to avoid pregnancy for a period afterwards.
Surgical Treatment
Surgery is needed if there is significant bleeding, the tube has ruptured, or medical treatment is not suitable. It is usually done by laparoscopy (keyhole surgery). The surgeon may:
- Remove the affected tube (salpingectomy), or
- Open the tube and remove the pregnancy (salpingostomy) to try to preserve the tube
In an emergency with heavy bleeding, open surgery may be necessary.
Recovery After an Ectopic Pregnancy
Recovery depends on the treatment. After keyhole surgery, many women go home within a day or two and return to normal activities within a couple of weeks. Your doctor will advise on follow-up tests, rest, and when it is safe to try for another pregnancy.
Emotional recovery matters as much as physical recovery. Grief, anxiety and guilt are common, and you don’t have to cope alone. Talk to your doctor about counselling and support.
If your blood group is Rh-negative, you may need an anti-D injection after an ectopic pregnancy.
Future Fertility and Pregnancy
Most women who have had an ectopic pregnancy go on to have a healthy pregnancy, even after losing a tube. The chance of another ectopic pregnancy is higher than average, so in future pregnancies you should have an early scan (usually around 6 to 7 weeks) to confirm the pregnancy is in the uterus.
Can Ectopic Pregnancy Be Prevented?
Not always, but you can lower some risks by:
- Avoiding smoking
- Practising safe sex and getting infections such as chlamydia treated promptly
- Seeing a doctor early in any new pregnancy if you have had an ectopic pregnancy or tubal surgery before
Not a true period, but irregular bleeding or spotting can be mistaken for one. If you have a positive pregnancy test with bleeding, see a doctor.
A transvaginal scan can often show the pregnancy location from about 5 to 6 weeks, but very early on it may not be visible and repeat tests may be needed.

No. An ectopic pregnancy cannot survive or be relocated, and treatment is needed to protect the mother's health.
Sometimes hCG falls naturally, but this can only be judged with close monitoring by a doctor. Never wait at home to see.
