Ectopic pregnancy
A pregnancy in which the fertilised egg implants outside the uterus. The fertilised egg can't survive outside the uterus. If left to grow, it may damage nearby organs and cause life-threatening loss of blood. Often, the first warning sign of an ectopic pregnancy is pelvic pain. Light vaginal bleeding may also occur. If blood leaks from the fallopian tube, you may feel increasing abdominal pain, an urge to have a bowel movement or pelvic discomfort. An ectopic pregnancy is one that occurs outside the womb, usually in one of the fallopian tubes. Because the fetus cannot survive and the mom could suffer life-threatening internal bleeding,ectopic pregnancies, which may account for as many as one in 40 pregnancies, are terminated at the earliest sign.
