A fertilized egg implanting and developing outside the uterus, often in the fallopian tubes, is a serious medical condition known as an ectopic pregnancy. In rare cases, it can occur in other areas like the ovary or abdominal cavity. As the pregnancy progresses, it can lead to pain, bleeding, and life-threatening complications for the woman. Ectopic pregnancies cannot reach full term and pose a significant risk to the woman's health. If not treated, they can cause the fallopian tube or the organ where the pregnancy is located to rupture, resulting in severe internal bleeding.
