Wait, 40 weeks is not 10 months, there are 4 1/4 weeks in a month so that makes it 9 1/2 months. Where does the 1/2 month come in? Pregnancy starts about 2 weeks after the last period, but to make it easy doctors start counting from the last period, not from time of conception. So conception really happens at '2 weeks' pregnancy.
This is just a way of calculation the period of pregnancy that everybody uses - to change it now would be impossible, or at least very difficult.

Look at a calendar, 40 weeks will add up to about 9 months and not 10, because not all months have exactly 4 weeks in them, all but Feb. have a little bit more.

first of all, I hear ya! lol ;-)
But actually, there are 4.3 weeks in a month, on average.
So if you take 4.3 weeks times 9 you get 38.7 weeks.
And actually, doctors start "counting" your pregnancy from the date of your last period, which is nearly TWO WEEKS before most women get pregnant. If you count those two weeks before you were even pregnant, you get about 40 weeks. So pregnancy is really about 9 months that you are actually pregnant. For those unlucky souls who are two weeks late when they deliver, its 9.5 months, though.
Anyway, it seems like a LIFETIME, doesn't it? I am 9 weeks along and really wish I could skip ahead to my 7th month or something right now.

Both, lol. 40 weeks = 9 LUNAR months. And remember that not all months have 4 weeks in them. Some have 5.

unquestionably that is 9 and a 0.5 months with the aid of fact your no longer technically pregnant the 1st 2 weeks of that 40 weeks. that is with the aid of fact that is lunar months, no longer calendar months. yet everywhere from 38 to 40 two weeks is complete term so it coudl be 9 or 10 actually.

Because months aren't four weeks long exactly, other wise we'd have 13 months in a year. And, the first two weeks of the pregnancy is the two weeks after your period and you're not even pregnant then. So technically you're only pregnant for 38 weeks.

Because, they count from the first day of your last cycle, and two weeks after ovulation, when it takes two week to implant into your uterus. Which is a total of 4 weeks, 1 month. So in reality it is 9 months you are pregnant, but 10 months for conception/implant period.
