Uh, actually, no it doesn't.
Well, okay, maybe it varies by, like ... a week, but generally, it's 9 months for, well, EVERYBODY, unless the baby is born prematurely or there's some complication.
lol, how old are you, Moo?
Doctors say predicted date of birth is March 8th, and she's already over 8 weeks pregnant.
7 months.
Hey, that adds up to (early) March (considering today is the last day of July)!
