What Is an Ectopic Pregnancy? Causes, Symptoms, and Treatment

Understanding Ectopic Pregnancy

An ectopic pregnancy occurs when a fertilized egg implants outside the uterus — most often inside a fallopian tube. Because these tubes are narrow and not designed to support a growing embryo, the pregnancy cannot continue safely.

In rare cases, an ectopic pregnancy can occur on the ovary, cervix, or abdominal cavity, which can cause severe internal bleeding or organ damage if untreated. These pregnancies are not viable and require urgent medical care.

Early recognition and medical treatment are critical — untreated ectopic pregnancy can be life-threatening.

Early Signs and Symptoms

At first, an ectopic pregnancy may resemble a normal pregnancy, but as it develops, symptoms often become more serious.
Common signs include:

  • Light vaginal bleeding
  • Pelvic or abdominal pain (often sharp or one-sided)
  • Shoulder pain (caused by internal bleeding irritating the diaphragm)
  • Weakness, dizziness, or fainting
  • Low blood pressure or rectal pressure

If you experience sudden, severe abdominal pain or feel faint while pregnant, call 911 or go to the nearest emergency room immediately.

What Causes an Ectopic Pregnancy?

Ectopic pregnancies develop when the fertilized egg cannot move through the fallopian tube to reach the uterus. The most common causes and risk factors include:

Risk Factor Explanation
Previous Ectopic Pregnancy Scarring or damage to fallopian tubes increases recurrence risk.
Pelvic Inflammatory Disease (PID) Infection can cause inflammation and block the fallopian tubes.
Endometriosis Tissue growth outside the uterus can interfere with egg movement.
Tubal or Pelvic Surgery Scar tissue can narrow or block the tubes.
Fertility Treatments (IVF) Slightly increases risk of abnormal implantation.
Smoking or Age Over 35 Reduces fallopian tube function and affects egg transport.

Treatment Options

Treatment depends on the location, size, and timing of the ectopic pregnancy.

1. Medication (Methotrexate)

  • Used when detected early and no rupture has occurred.
  • Stops the growth of the pregnancy tissue.
  • Administered as an injection, followed by blood tests to track hCG levels.

2. Surgery (Laparoscopy)

  • Required if the fallopian tube has ruptured or bleeding occurs.
  • Involves removing the ectopic pregnancy through small incisions.
  • In some cases, the affected fallopian tube must be partially or fully removed.

Recovery typically takes 2–6 weeks, depending on severity and procedure type.

Ectopic Pregnancy and Abortion Access

An ectopic pregnancy is not a viable pregnancy, and prompt treatment is considered medically necessary to save the patient’s life.

In California, treatment for ectopic pregnancy is fully legal and supported under state law.
If you live in another state, consult a qualified medical professional about your options.

When to See a Doctor

Call your provider immediately if you:

  • Experience unusual pelvic pain or bleeding during pregnancy
  • Have a history of fallopian tube surgery, PID, or ectopic pregnancy
  • Feel faint, dizzy, or experience shoulder pain

Frequently Asked Questions

1. Can an ectopic pregnancy move to the uterus?

No. Once implanted outside the uterus, it cannot relocate or become viable.

2. How soon can an ectopic pregnancy be detected?

Often within the first 4–6 weeks of pregnancy through blood tests and ultrasound.

3. Can I get pregnant again after an ectopic pregnancy?

Yes, many women go on to have healthy pregnancies. Your provider can advise on timing and monitoring.

4. What’s the recovery time after treatment?

Most recover in 2–6 weeks, depending on whether medication or surgery was required.
