I think you should take a pregnancy test if you are two weeks late. It should tell you whether you are pregnant or not. To help you, look at a calender and mark the first day of your last period for about three months then count how many days between each period start day. The half way days between periods you are fertile. if your period starts every 28 days then you are fertile around the 14th day.
