O00: Ectopic pregnancy

O00.8: Other ectopic pregnancy

Pregnancy can occur when at least one mature egg cell is fertilized. A woman has two ovaries. Each ovary normally takes turns maturing one egg every month. These eggs may be fertilized by sperm. The eggs pass to the uterus through the fallopian tube.

The fertilized egg cell continues to develop in the first part of pregnancy. This is known as an embryo. The embryo needs more and more space as time goes on. Usually, an embryo can only continue to develop into a child in the normal place within the uterus.

If the embryo is not continuing to develop in the normal place within the uterus, this can lead to various problems. For example, you may have pain in the lower abdomen. Irregular bleeding from the vagina may also occur.
