Hey ladies, was wondering if you could clear up for me when we go into 3rd tri? Some websites day it's 27 weeks and some say 28 weeks? Help!
Opinion seems to vary! I took it as 28 weeks, just as it's definitely the 3rd trimester at that point!
My doctor (US) uses 28 weeks as the start of first trimester. However, I go with the real timeline. 40 weeks divided by 3 means each trimester is 13.3 weeks long... meaning almost-27 weeks is third tri... So I round up and move over at 27 weeks.
When my mom was pregnant with me, you were due after 39 weeks, so 13 weeks started the second trimester, and 26 started the third. Since they added a week to pregnancy, they really messed with our trimesters in the process.
