Pregnancy is typically broken into three periods, or trimesters, each of about three months. Each trimester is defined as 14 weeks, for a total duration of 42 weeks, although the average duration of pregnancy is 40 weeks.
If you calculate a month as being four weeks, that makes 10 months of pregnancy in every 40 weeks. The problem with this calculation is that it has 28 day months, which is not the norm in our calendar months. There is also the issue of when you actually are pregnant.
