its 27 weeks then that's what I am going by i know i have my glucose testing coming up as well and that is done in the 3rd trimester

@mom13, I have the same app. and mine says my 2nd trimester ends tomorrow.

I just divide 40 by 3. There are just over 13 weeks per trimester. Which means it would be about week 27.

@their.bomb.ass.mom, yeah I agree with you. It's not much of a difference either way. Pregnancy can go all the way to 42 weeks. So give or take a week

my doctor says the beginning is 28 weeks. I just go by 28 since its only a week difference.

@jream_girl, @lpoliseo I thought the same thing

My doctor said 27 weeks

27 weeks is the beginning of the 3rd trimester, and that trimester will last until your 40th week.

these are confusing lol

28 weeks I believe

28 weeks
