The three prenatal periods (germinal, embryonic, and fetal) are not the same as the three trimesters in terms of length. The first trimester includes both the germinal and embryonic periods and lasts from conception to week 12. The second trimester lasts from week 13 to week 27, and the third trimester lasts from week 28 until birth. The fetal period begins at the end of the embryonic period, which is in the first trimester.
