Gestation age vs fetal age

Gestation age-sperm penetrates the egg and zygote is formed

Zygote (fertilized egg) travels from fallopian tube to uterus

During this time, egg divides into cells - called a morula

Continued dividing and morula - called a blastocyst - embeds in the uterus anywhere from 6-12 days after conception

This begins the embryonic stage and fetal age begins
