Duration of pregnancy The average duration of pregnancy from fertilization to birth was 38 weeks (fetal period). The average duration of pregnancy from the beginning of the last menstrual period before birth is 40 weeks (maternity period). Using OB period is more common in medicine, as fertilization date, as a rule, difficult to define. It is also customary to embryonic period (first 8 weeks from fertilization) and fetal (from 9 weeks before delivery) periods of development.
Embryonic period The embryonic period lasts from the moment of fertilization to the end of 8 weeks of the embryonic period (10 week OB period). During the embryonic period, fertilization occurs, split (the formation of multicellular), implantation (introduction into the uterus), gastrulation (formation of germ layers), organogenesis (forming organs), placentation, and other processes. Embryo at 4 weeks after fertilization. (Image from gestational age of 6 weeks). Fetus at 8 weeks after fertilization. (Image from gestational age of 10 weeks)
Fetal period Fetal period lasts from 11 weeks to term obstetric delivery. By the early fetal period in the fetus are formed all organ systems (development takes place within the system generated), in appearance resembles a baby fetus, there is an intensive growth of the fetus and the change in body proportions. Fetus at 18 weeks after fertilization. (Image from gestational age of 20 weeks). Fetus at 38 weeks after fertilization. (Image from gestational age of 40 weeks).
