When does 3rd trimester start?

Question

I'm 26 weeks today and my apps are telling me "welcome to your third trimester" but I thought third started at 28 weeks

Answer

Usually 27 weeks

Answer

Ya I think glow divides the trimesters up by days, because mine said third trimester in the middle of my 26th week lol. But I say 27 weeks officially. When I hit 27 weeks I was exactly 3 months away from my due date so that's what I'm sticking with lol.

Answer

Yeh I noticed it at 26 weeks and a couple days I think... But my chart shows 27 weeks also
