Symptoms

You may not notice any symptoms at first. However, some women who have an ectopic pregnancy have the usual early signs or symptoms of pregnancy — a missed period, breast tenderness and nausea.

If you take a pregnancy test, the result will be positive. Still, an ectopic pregnancy can't continue as normal.

As the fertilized egg grows in the improper place, signs and symptoms become more noticeable.

Early warning of ectopic pregnancy

Often, the first warning signs of an ectopic pregnancy are light vaginal bleeding and pelvic pain.

If blood leaks from the fallopian tube, you may feel shoulder pain or an urge to have a bowel movement. Your specific symptoms depend on where the blood collects and which nerves are irritated.

Emergency symptoms

If the fertilized egg continues to grow in the fallopian tube, it can cause the tube to rupture. Heavy bleeding inside the abdomen is likely. Symptoms of this life-threatening event include extreme lightheadedness, fainting and shock.

When to see a doctor

Seek emergency medical help if you have any signs or symptoms of an ectopic pregnancy, including:

• Severe abdominal or pelvic pain accompanied by vaginal bleeding
• Extreme lightheadedness or fainting
• Shoulder pain
