In most ectopic pregnancies, the egg settles in the fallopian tubes. This is why ectopic pregnancies are commonly called "tubal pregnancies. None of these areas has as much space or nurturing tissue as a uterus for a pregnancy to develop. As the fetus grows, it will eventually burst the organ that contains it. This can cause severe bleeding and endanger the mother's life. A classical ectopic pregnancy does not develop into a live birth.
