When does the first trimester end? People been telling me different things and when I look it up I…

The 12th week is the last week of your 1st trimester. Making 13weeks the start of your second

I don't go by the charts because they sneak in an extra week here and there. Like on some charts the second trimester doesn't start til 14 weeks which doesn't make sense because that would be 5 weeks in the 3rd month. I say 13 is the start of the second and you're actually pregnant for 10 months with that calculation tho

I've heard the fourteenth week is the beginning go your second trimester

Of*

Correct

that's the same thing

Some charts will be different by a week, with some saying 13 and some saying 14. Just think of it like your due date....it can be off....it's just to kind of give you a better idea of when things are expected to happen.

13th - 14th
