When is it officially the firs week of the second trimester. 13 or 14 weeks??

Wk13😉 (..Trust me) a new trimester dosen't start in the 2nd wk of a new month. And dont go by Google charts

Week 13 is the start of the second trimester

Someone posted this and it helped me .

My OB said 14 as well.

It really doesn't matter. Whatever you want to go with.

Yea cause your gonna get a lot of different answers lol

They say 14 because they counting the 10th month cause were actually pregnant for 10 not 9 if you count the ovulation week but doctors start at missed period so that’s the fourth week . So by books it’s 14 but by doctors going off of period it’s 13

@prestonjeanetta0120, thank you! I thought I remembered 13 from my last pregnancy but all the apps I have now say 14. Thank you again😊

@coralinesmommy, no problem it can confusing when people and apps and everything else is saying different things lol !

@prestonjeanetta0120, yessss exactly!
