Can ectopic pregnancy be prevented?

Some ectopic pregnancies occur without a known avoidable cause. Prevention efforts cannot ensure where a fertilised egg implants, so recognising a pregnancy early and responding to warning signs remain essential.

An ectopic pregnancy happens when a fertilised egg implants outside the main cavity of the uterus, most often in a fallopian tube. A pregnancy in this location cannot develop normally and can cause dangerous internal bleeding if the tube ruptures.

Damage or narrowing in a tube can interfere with movement of the fertilised egg. Pelvic infection, previous tubal surgery and a previous ectopic pregnancy can raise risk, but their presence does not mean an ectopic pregnancy will occur.

Using barrier protection during sex and arranging testing when a sexually transmitted infection is possible can reduce infections that may lead to pelvic inflammatory disease and tubal scarring. Complete any prescribed treatment and follow advice about partner testing or treatment.

After a positive pregnancy test, tell a clinician about previous ectopic pregnancy, tubal surgery, pelvic inflammatory disease or fertility treatment. They may arrange blood tests and an early ultrasound to locate the pregnancy. Monitoring finds an ectopic pregnancy sooner; it does not prevent implantation.

Get urgent medical assessment for pelvic or abdominal pain, vaginal bleeding, shoulder-tip pain, marked dizziness or weakness when pregnancy is possible. Symptoms may begin before a person knows they are pregnant.

Call emergency services for sudden severe pain, fainting, collapse, confusion or signs of shock such as pale, cold or clammy skin. Do not drive yourself if you feel faint or seriously unwell.

Ask when an ultrasound can reliably check the pregnancy's location, whether repeat hormone tests are appropriate, and exactly which symptoms should take you to emergency care. If you have had an ectopic pregnancy, also discuss a plan for monitoring the next pregnancy.
