Script: 9 MESES

El feto inicia el proceso del parto segregando grandes cantidades de una hormona llamada estrógeno y así empieza la transición de feto a recién nacido.

El parto se distingue por fuertes contracciones del útero, que terminan en el parto.

All ages referenced to fertilization, not last menstrual period. One month = 4 weeks.
