40 Weeks = 9 Months

Was talking to a couple friends and think that maybe we solved this mystery.

As some months have 4 1/2-5 weeks, it is possible to add on a couple extra weeks-ish.

This was established early.  However, I was still not convinced, as it still didn't tack on 4 extra weeks.

BUT, and I don't know if this is the final reason--but our current hypothesis is that it actually has to do with the first 2 weeks of the pregnancy.

These two weeks, you are not actually pregnant!  The doctors start counting from the 1st day of your previous period, not from date of conception.

So, if this is taken into consideration, than, yes, technically, you are only preggo for 9 months.  If you look at months, and not weeks.

Yoda told me that she never figured out why they counted the way they did--in two pregnancies.

So, tip is to just not let it worry you--stick with the weeks, bypass the details, and concentrate on the pregnancy itself.

Sounds like a good plan.  :-)
