when does an ectopic pregnancy occur
Ectopic Pregnancy: Symptoms, Causes, Risks and Treatment. An ectopic pregnancy occurs when the fertilized egg attaches itself in a place other than inside the uterus. Almost all ectopic pregnancies occur in the fallopian tube, and are thus sometimes called tubal pregnancies. The fallopian tubes are not designed to hold a growing embryo; thus, the fertilized egg in a tubal pregnancy cannot develop properly and must be treated. An ectopic pregnancy happens in 1 out of 50 pregnancies.
