In most pregnancies, the fertilized egg travels through the fallopian tube to the womb (uterus). If the movement of the egg is blocked or slowed through the tubes, it can lead to an ectopic pregnancy. Things that may cause this problem include:
If the area around the abnormal pregnancy ruptures and bleeds, symptoms may get worse. They may include:
Fainting or feeling faint
Intense pressure in the rectum
Low blood pressure
Pain in the shoulder area
Severe, sharp, and sudden pain in the lower abdomen
Exams and Tests
The health care provider will do a pelvic exam. The exam may show tenderness in the pelvic area.
A pregnancy test and vaginal ultrasound will be done.
HCG is a hormone normally produced during pregnancy. Checking the blood level of this hormone (quantitative HCG blood test) can diagnose pregnancy. If the blood level of HCG is not rising fast enough, your doctor may suspect an ectopic pregnancy.
Ectopic pregnancy is life-threatening. The pregnancy cannot continue to birth (term). The developing cells must be removed to save the mother's life.
You will need emergency medical help if the area of the ectopic pregnancy breaks open (ruptures). Rupture can lead to bleeding and shock, an emergency condition. Treatment for shock may include:
Fluids given through a vein
Raising the legs
If there is a rupture, surgery is done to stop blood loss and remove the pregnancy. In some cases, the doctor may have to remove the fallopian tube.
If the ectopic pregnancy has not ruptured, treatment may include:
Medicine that ends the pregnancy, along with close monitoring by your doctor
One out of three women who have had one ectopic pregnancy are later able to have a baby. Another ectopic pregnancy is more likely to occur. Some women do not become pregnant again.
The likelihood of a successful pregnancy after an ectopic pregnancy depends on:
The woman's age
Whether she has already had children
Why the first ectopic pregnancy occurred
When to Contact a Medical Professional
Call your doctor or nurse if you have:
Abnormal vaginal bleeding
Lower abdominal or pelvic pain
Most forms of ectopic pregnancy that occur outside the fallopian tubes are probably not preventable. You may be able to reduce your risk by avoiding conditions that may scar the fallopian tubes. These steps include:
Practicing safer sex by taking steps before and during sex, which can prevent you from getting an infection
Getting early diagnosis and treatment of all infections caused by sexual relations (STDs)
