The stages of an ectopic pregnancy may be thought of
as fertilization, abnormal positioning of the fetus outside the uterus, development of symptoms, death of the fetus through miscarriage or medical treatment.
In the “second stage” of an ectopic pregnancy, the fertilized egg implants in one of the fallopian tubes or sometimes in an ovary, the cervix or the abdomen.
Next, the woman may experience symptoms such as abnormal vaginal bleeding or pain in the lower back or pelvic region as the body removes the tissue of the embryo. If the fetus develops large enough, it may create a rupture causing severe bleeding.
Because the fetus cannot receive adequate blood flow, it cannot survive. In this last of the “stages” of ectopic pregnancy, sometimes the tissue is absorbed with few or no complications. Other times a miscarriage may result, but in some cases, medical intervention may be required to protect the woman’s health.
