At three-quarters of an inch long, the fetus is still in the embryonic period, which lasts from the second to the eighth week of pregnancy. During this stage, major organs and body structures begin to form. The germinal period is the first two weeks after conception, and the zygotic period is another name for the germinal period. The fetal stage begins at the ninth week and lasts until birth when the baby's organs and systems continue to develop and mature.
