Key message: An ectopic pregnancy grows outside the uterine cavity, most often in a fallopian tube. It cannot develop normally and may rupture, so pain or bleeding with a positive pregnancy test requires timely assessment.
Get urgent help: Call emergency services or attend emergency care for severe or one-sided pain, shoulder-tip pain, fainting, collapse, marked dizziness, pallor, heavy bleeding or feeling suddenly very unwell. Do not drive yourself if collapse is possible.
What symptoms can occur?
- One-sided or general lower-abdominal pain.
- Vaginal bleeding or brown discharge.
- Shoulder-tip pain.
- Pain when opening the bowels or passing urine.
- Dizziness, fainting or collapse.
- Sometimes no symptoms before an ultrasound finding.
Who has a higher chance?
- Previous ectopic pregnancy.
- Tubal damage, pelvic inflammatory disease or tubal surgery.
- Pregnancy after fertility treatment.
- Pregnancy with an intrauterine device in place, although pregnancy itself is uncommon with an IUD.
- Smoking and increasing age.
- No recognised factor in many cases.
How is it diagnosed?
A positive pregnancy test with no pregnancy seen inside or outside the uterus is called a pregnancy of unknown location. Follow-up must continue until the location or outcome is known.
- Symptoms, examination and a transvaginal ultrasound.
- Serial beta-hCG tests when the location is not yet clear.
- Blood group, full blood count and other tests according to symptoms.
- Repeat ultrasound because one early scan may be inconclusive.
What treatment options exist?
- Expectant management for selected stable patients with low and falling hCG and reliable follow-up.
- Methotrexate injection for suitable unruptured ectopic pregnancy with no contraindication.
- Laparoscopic surgery when rupture is suspected, symptoms or hCG are concerning, methotrexate is unsuitable or the patient prefers surgery.
- Emergency open surgery and blood transfusion rarely when severe internal bleeding occurs.
What follow-up is needed after methotrexate or observation?
hCG is checked until the agreed safe endpoint. Pain can occur during treatment, but worsening or collapse symptoms need emergency assessment.
Avoid folic-acid supplements, alcohol and pregnancy for the advised interval after methotrexate; follow the exact service instructions.
What happens to the fallopian tube during surgery?
The affected tube may be removed (salpingectomy), especially when the other tube looks healthy. In selected fertility circumstances, the pregnancy is removed while leaving the tube (salpingotomy), but persistent tissue and another ectopic are more likely and hCG follow-up is essential.
The choice depends on bleeding, tube damage, the other tube and fertility history.
What about RhD and emotional recovery?
Blood group is checked, and Anti-D is offered in circumstances defined by gestation, treatment and local protocol. Pregnancy loss can cause grief, anxiety and trauma; emotional support is part of care.
Seek urgent mental-health help for self-harm thoughts.
What is the chance in a future pregnancy?
Many people later have an intrauterine pregnancy, but the chance of another ectopic is increased. Contact maternity care after the next positive test for an early location scan, usually around 6–8 weeks according to the service.
Do not wait for pain before arranging follow-up.
Frequently asked questions
Can hCG alone diagnose an ectopic pregnancy?
No. The trend is interpreted with symptoms and ultrasound.
Can an ectopic pregnancy move into the uterus?
No. A confirmed ectopic cannot be moved or continue normally.
Does removing one tube cause infertility?
Many conceive with one healthy tube; fertility also depends on age and the remaining tube and other factors.
Can an ectopic occur with IVF?
Yes, and rarely an intrauterine and ectopic pregnancy can coexist.
When can we try again?
Timing depends on treatment, recovery and methotrexate exposure; follow the individual plan.
Your next step
Any positive pregnancy test with pain or bleeding deserves prompt advice. Bring previous ectopic, fertility and operation records. Emergency warning signs require hospital care immediately.
