Typical signs of ectopic pregnancy include abdominal pain, vaginal bleeding and amenorrhea, or absence of menstrual periods. About 50 percent of women with this condition do not develop all the three signs, states MedicineNet. Other signs include sharp abdominal cramps, pain on one side of the body, vomiting and dizziness, according to WebMD.
An ectopic pregnancy is a pregnancy in which a fertilized egg does not implant in the main cavity of the uterus. Also called a tubal pregnancy, an ectopic pregnancy usually occurs in one of the fallopian tubes, which are the tubes that conduct eggs from the ovaries to the uterus, states Mayo Clinic. In its early stages, an ectopic pregnancy often feels like a normal pregnancy, with typical signs of early pregnancy such as increased urination, nausea and tender breasts, according to WebMD.
Doctors normally discover an ectopic pregnancy by the eighth week following conception. Women who experience an ectopic pregnancy require emergency treatment to prevent hemmorhage and preserve their ability to have children in the future, explains WebMD.
Causes of ectopic pregnancy include scarring and inflammation of the fallopian tubes, birth defects and genetic abnormalities, states Healthline. A history of sexually transmitted disease, endometriosis, multiple abortions or pelvic inflammatory disease increase the risk of ectopic pregnancy.
