36 weeks/9 months

Well, it depends on how you count it. These days, most practitioners determine your due date by counting 40 weeks from the first day of your last menstrual period. Keep in mind that you're not actually pregnant for the first two weeks because you haven't even ovulated yet, and you don't usually find out you're pregnant until you're about 4 or 5 weeks along. But this is how most people count it. And forty weeks adds up to about nine calendar months (30 or 31 days each) or ten lunar months (28 days each). In order to make it easy to count the months, a lot of guidebooks and web sites, including this one, will count the months of pregnancy as lunar months, so that every four weeks, you're another month along. Counting this way, you will be ten lunar months pregnant by the time 40 weeks is up.

i've had some discussions with some friends and it is confusing especially for men who have not had kids and women who have not been pregnant to understand what 36 wks means.

the easiest way is to say pregnancy is 40 wks and i'm at 36 wks. the difficult part is when you discuss months. and explaining that after 37 wks it is safe to have the baby because that is considered full term.
