Ectopic pregnancy, also known as eccyesis or tubal pregnancy, is a complication of pregnancy in which the embryo attaches outside the uterus. Signs and symptoms classically include abdominal pain and vaginal bleeding. Less than 50 percent of women have both of these symptoms. The pain may be described as sharp, dull, or crampy. Pain may also spread to the shoulder if bleeding into the abdomen has occurred. Severe bleeding may result in a fast heart rate, fainting, or shock. With very rare exceptions the fetus is unable to survive.
Chlamydia is a common sexually transmitted disease (STD). Most people have no symptoms, but Chlamydia can cause serious damage to a woman’s reproductive organs. Symptoms of Chlamydia include thin vaginal discharge and burning when urinating. Long-term irritation may cause lower abdominal pain, inflammation of the pelvic organs, and pelvic inflammatory disease (PID).
