Script: Embryo začína byť v tomto čase fyzicky aktívnejšie.

Pohyby môžu byť pomalé alebo rýchle, jednotlivé alebo opakované, spontánne alebo reflexívne.

Otáčanie hlavou, naťahovanie krku a dotýkanie sa tváre rukou sa dejú čoraz častejšie.

All ages referenced to fertilization, not last menstrual period.
