Why pregnancy count 40 weeks?

Sagot :

I think it is because pregnancy can last for 9 months.
For every month there are estimated 4 weeks.
9 months x 4 weeks = 36 weeks
Maybe 40 weeks is the estimated number of weeks pregnancy can last.
Note: 36 weeks is just estimated. I'm sure it is not exact, it is insufficient.

It is because it includes the time of conception up to period wherein the fetus is gaining weight and immunity
