There's also not a full 4 weeks in each month....
10 lunar months, 9 calendar months. Remember that your baby is really two weeks younger than whatever week you are in. So when you get the earliest positive pregnancy test and the doc says "You're 4 weeks!" baby is actually measuring at 2 weeks old (gestationally). So yes, you will be pregnant 10 months. LOL! It is confusing, but rest-assured your doc isn't being strange or anything.
ok...that makes much more sense. I didnt think about the extra days and all...thank you very much :)
Also they used to say 9 months, but that means 9 calendar months, which is closer to 40 weeks, rather than 36, because most months have 4 weeks + 2 or 3 days, which help make up the extra time. Just some info I read in what to expect when you are expecting.
Thank you...It makes a little more sense to me now :)
Baby due date
The unborn baby spends around 38 weeks in the uterus (womb), but the average length of pregnancy, or gestation, is calculated as 40 weeks. This is because pregnancy is counted from the first day of the woman’s last period, not the date of conception which generally occurs two weeks later. Since some women are unsure of the date of their last menstruation (perhaps due to period irregularities), a pregnancy is considered full-term if birth falls between 37 to 42 weeks of the estimated due date.
A baby born prior to week 37 is considered premature, while a baby that still hasn’t been born by week 42 is said to be overdue. In many cases, labour will be induced in the case of an overdue baby.
I got this information from the better health website.
