The mechanism of bleeding in an ectopic pregnancy occurs when the fertilized egg implants outside of the uterus, typically in the fallopian tube. As the pregnancy progresses, the growing embryo can cause the fallopian tube to stretch and eventually rupture, leading to internal bleeding. This is a medical emergency that can be life-threatening if not treated promptly. Other potential causes of bleeding in ectopic pregnancy include the embryo implanting in other locations such as the ovaries or abdomen, which can also lead to internal bleeding.
