About Ectopic Pregnancy
The uterus, or womb, is the place where a fetus grows during pregnancy. In an ectopic pregnancy, the fertilized egg grows in the wrong place outside the uterus. It usually occurs in the fallopian tubes. These tubes carry eggs from the ovaries to the uterus. Sometimes, an ectopic pregnancy can occur in the ovaries, abdominal cavity, or the lower part of the uterus (cervix).
Ectopic pregnancies can't end in a healthy pregnancy because the egg cannot grow. If the pregnancy continues, the fallopian tube can burst. This can cause internal bleeding, which can be a life-threatening emergency that needs immediate surgery.
An ectopic pregnancy often happens because there is a problem with your fallopian tubes. But sometimes it's not clear why an ectopic pregnancy happens.
Factors that may increase your risk for an ectopic pregnancy can include:
- Previous ectopic pregnancy
- Prior pelvic, abdominal, or fallopian tube surgery
- Certain sexually transmitted infections (STIs)
- Pelvic inflammatory disease
- Endometriosis
- Becoming pregnant while using an intrauterine device (IUD) for birth control
- Becoming pregnant after a tubal ligation
Other factors that may increase your risk can include:
- Smoking
- Being older than age 35
- Infertility treatments
You may not notice any symptoms at first. Or you may have some of the usual signs of pregnancy such as a missed period, breast tenderness, or nausea.
Early signs of an ectopic pregnancy may be light vaginal bleeding and pelvic pain. Ectopic pregnancy can be a medical emergency. Get medical care right away if you have these signs:
- Abdominal (belly) pain
- Shoulder pain
- Vaginal bleeding
- Feeling dizzy or faint
An ectopic pregnancy can't be diagnosed without blood tests and an ultrasound. Your health care provider will do a pregnancy test to confirm that you're pregnant. They may do a pelvic exam to check for areas of pain, tenderness, or a mass.
An ectopic pregnancy needs treatment to stop any damage to your organs. Your provider will use medicine or surgery to take out the ectopic tissue.
Losing a pregnancy can be devastating. An ectopic pregnancy is like a miscarriage, but it must be treated to prevent problems. People cope with grief in different ways. It may be helpful to discuss your feelings with your provider or a counselor. Many women who have had ectopic pregnancies go on to have healthy pregnancies later.

When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.
Research on Ectopic Pregnancy
116 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.
What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
