Things may have changed since I had my last child (he's now 11), but it used to be a pregnancy was calculated as 40 weeks, and this included two weeks at the beginning when you weren't actually pregnant at all as they took the date from the first day of your last period.
Anyway, it used to be that 13 weeks was the last week of the 1st trimester and 14 is the start of the second trimester.
As I say, if it's not worked out as 40 weeks anymore this will be different.
This is a good guide to how your body will change and how your baby is developing:

Good luck with your pregnancy.
