What do you consider the start of the 3rd Trimester?

Question

I always thought the 3rd trimester started at 28 weeks, but this shows 27 weeks, and Glow is telling me 26 🙃 so I just want to know what you ladies consider the start of the 3rd trimester and why.

Answer

My doctor says 27 weeks so that’s what I go with 🤷🏼‍♀️

Answer

Depends on the system.
0w0d-0w6d = week 1
1w0d-1w6d = week 2
2w0d-2w6d = week 3
Etc. 
The two different systems can often lead to a seemingly week-long disparity when you want to look these things up, so you need to beware of the system that’s in place.

Answer

To be technical, if you divide 40 by 3 you get 13.3. So 26.6 would TECHNICALLY be the beginning of the third trimester. I just round up to 27 and so do most doctors
