When do people class as 3rd trimester ?, I’ve always said 27weeks

Question

All apps I use say 27weeks is the start of the 3rd trimester and that’s what I’ve always followed! Just want to see what other people think 😆 I’ll be 26weeks on Thursday

Answer

Technically pregnancy is 40 weeks. If you divide by 3, each trimester is 13.3333 weeks long. So 2nd trimester starts at week 13.3333, 3rd trimester then starts at 26.6666 weeks (so basically 27)

Answer

I counted 27 weeks as 3rd Tri to make myself feel better 😆😆 . But I think 28 weeks is more accurate .

Answer

I found this one on here. 28 weeks. But you can technically say your in the third as you are entering your 28th week of pregnancy. A few days doesn’t make a big difference

Answer

I think when you are in your 28th week you are in your third trimester. So 27 complete weeks. But I’ve also heard it go both ways 🤷🏼‍♀️
