The unborn baby spends around 38 weeks in the uterus, but the average length of pregnancy, or gestation, is counted at 40 weeks. Pregnancy is counted from the first day of the womans last period, not the date of conception which generally occurs two weeks later.
Is it 9 months of pregnancy or 10?
Is pregnancy nine or 10 months long? Your 40 weeks of pregnancy are counted as nine months. But wait … there are four weeks in a month, which would make 40 weeks 10 months.
Why is it 9 months but 40 weeks?
Thats because months vary in days. Averaging 365 days over 12 months, your average month lasts 30 days and 10 hours. So 280 days (or 40 weeks) is actually nine months plus nearly a week.
Which month is best for delivery?
