In the first four weeks from conception, fetal growth of the ovum begins with development of the spinal cord, nervous system, gastrointestinal system, heart and lungs. By eight weeks, in the embryonic stage, the face is forming, arms and legs move, the baby's heart begins beating and the brain and other organs form.
Short answer: Conception occurs when the egg is released from the ovary at ovulation and meets (is fertilized by) the sperm waiting in the fallopian tube. One sperm burrows into the wall of the egg which signals cells to grow and develop. This is the moment of conception, occurring within about 24 hours of ovulation.
