An ectopic pregnancy is a pregnancy that occurs outside of the uterus. Most ectopic pregnancies occur within a fallopian tube. Other, less common locations may include the cervix, an ovary, or the abdominal cavity. This type of pregnancy cannot survive. Only the uterus can support the growth of a fetus and its placenta.

Images may be taken of your uterus and fallopian tubes. This can be done with a transvaginal ultrasound.
Treatment options include:
If the ectopic pregnancy is small and has not ruptured (burst), a medication that prevents further growth of the ectopic pregnancy may be advised.
Surgery may be needed, especially if the ectopic pregnancy has ruptured or if it is not in the fallopian tube. During the surgery, the pregnancy will be removed.
If the pregnancy is in the fallopian tube, the doctor may be able to repair the tube. In severe cases, the fallopian tube may need to be removed.
To help reduce your chance of an ectopic pregnancy:
Maintain safe sexual practices to avoid
sexually transmitted diseases (STDs)
, which can damage to the fallopian tubes and ovaries.
Get early diagnosis and treatment of STDs.
