13 weeks 1 day Am I still in the first trimester or second?

Thanks!

If you do the math, 40 weeks divided by 3 trimesters (40/3), you get 13 1/3 (thirteen and one third). If you divide a week into thirds (7/3), you get 2 1/3 (two and one third). So...TECHNICALLY, you start your second trimester at 13 weeks and 2 1/3 days :) If you're not a total numbers nerd like me though, most people consider the start of your thirteenth week to also be the start of your second trimester.

Congratulations! I'll be there in one two weeks! Cannot wait!!

2nd!
