Fetal Development Basics & Pregnancy

At 4 weeks, the cells of the fetus are specializing into a nervous system, hair, organs, and skin. At 12 weeks, the fetus is around 2 _ inches in size and makes movement on its own. At 20 weeks, the nervous systems functions, sex can be determined, and you will feel your baby move. At 28 weeks, the fetus weighs over 2 pounds and if born prematurely, would most likely be able to survive. At 32 weeks, the baby weighs 4 pounds and fat layers begin to develop under its skin. At 36 weeks, the lungs are almost fully developed and brain function is developing rapidly. At 37 weeks, a term pregnancy can be made.
