Early detection of ectopic pregnancy

An ectopic pregnancy develops outside the main cavity of the uterus, often in a fallopian tube. Early symptoms can include one-sided pelvic pain, vaginal bleeding, shoulder-tip pain, dizziness or discomfort when passing urine or stool. Some people have no symptoms at first. A pregnancy test can show pregnancy, but it cannot show its location. Clinicians may compare pregnancy hormone results over time and use a transvaginal ultrasound to look for the pregnancy and assess nearby structures.

Pelvic inflammatory disease can affect the fallopian tubes and is one condition your clinician may consider when reviewing risk. A symptom such as pelvic pain does not by itself establish ectopic pregnancy.

If you have a positive pregnancy test with pain or bleeding, contact a maternity or gynaecology service promptly. Take note of when symptoms began, where pain is located, how it changes, and whether bleeding is increasing. Bring details of your last menstrual period, prior pregnancies, surgery and any known tubal problems. Assessment may include repeat blood testing and a transvaginal ultrasound; the timing depends on symptoms and the findings.

Seek emergency help for sudden or severe abdominal or pelvic pain, fainting, marked weakness, shoulder-tip pain with bleeding, or trouble breathing. These symptoms can signal internal bleeding and need immediate assessment. Do not drive yourself if you feel faint. If an ectopic pregnancy is diagnosed, treatment may involve medicine, monitoring or surgery such as salpingectomy, depending on the pregnancy location, symptoms and test results.

Ask: Where is the pregnancy located? Do I need repeat hormone testing or another ultrasound? Which symptoms should send me to emergency care? What treatment options fit my results, and how will follow-up be arranged?
