Question: What Does Gestation Mean In Pregnancy?

Gestation is the period of time between conception and birth.

Can you calculate the exact day of conception?

Knowing the exact day of conception is a difficult thing. Sperm can live in a woman’s body for up to five days, making it impossible to calculate exactly when conception occurred.
