there are 40 weeks in pregnancy.
so if you divide that into three trimesters, you get 13 1/3 weeks.

here's a free online calculator that will tell you when each of your trimesters ends as well as your due date, estimated date of conception, etc.

the 13th week ends the 1st trimester. Once you turn 13 weeks then you will be in your second trimester

I believe the 12th week is the end of the first trimester.

the 12th ends it and the 13th begins the second trimester.

14th week begins the second trimester, so the first would end at week 13

I would think that as you are entering your 13th week, you have just completed your 1st trimester.
