Pregnancy
Five days after fertilization, cleavage (splitting ) has occurred several times, forming a ball of 128 cells, or blastocyst. After eight to ten days, the blastocyst implants in the endometrium and is called an embryo. Implantation is the process by which an embryo burrows into the endometrial lining of the uterus. An umbilical cord connects the placenta to the developing baby to provide nutrients.
Embryonic Development

Fetal Development
|
Embryonic Development is when Organogenesis takes place. Organogenesis is when the embryos organs begin to take proper form in the desired location. After eight weeks of this phase has been completed, the embryo is now a fetus.
|
Fetal Development occurs in the amnion, a fluid-filled sac that cushions and stabilizes the fetus. This developmental phase occurs for 9 months.

Ectopic Pregnancy
Ectopic Pregnancy is a serious condition in which an embryo attaches and develops inside the fallopian tube. It can be caused by pelvic inflammatory disease or endometriosis. Ectopic Pregnancy can result in a ruptured fallopian tube, causing severe abdominal pain, bleeding, and shock. To reduce risks of acquiring an ectopic pregnancy, women should avoid getting sexually transmitted infections and consulting their doctor if an infection is suspected.
