3rd trimester question

When does the 3rd trimester start? I keep getting conflicting info. The pregnancy app I have on my phone says that I'm in the 3rd trimester this week which I know is bogus. Other websites say 27 weeks and others say 28 weeks! Why is this never clear? I had the same problem with trying to figure out when the 2nd trimester starts. Ugh! Either way, I can't believe I only one 2-3 weeks to go before I'm in the last trimester!!!

I'm not sure there is a specific date since neither 38 or 40 weeks is easily divisible into thirds. But my insurance counts 28 weeks 0 days as the start of the 3rd tri. So I guess that's what I will go with. ???

Not sure about you but for me this pg has flown by! I have a feeling I am going to be pretty surprised when I have a baby in my arms. Even though it is my third it just still seems so unreal.

I agree with 28 weeks. The time is just flying by this time.

Crazy how fast it is going. Less than 3 weeks Jenn and we will be in the third tri. I won't have moved yet and can't do or really buy anything baby related until we do lol Talk about leaving it last minute lol
I just checked Web MD which I use often for various things and they count 26 weeks. I wonder if it is because they figure from 38weeks you are actually at term.

I say go with which ever one you want :). Obviously there's not set rules on trimesters which is why everything says something different! I hate all the ways they count down pregnancy. Its all different! Months aren't really a month long and trimesters aren't really a third of your pregnancy! Sorry... For the outburst there lol.

I completely agree! If you divide you 40 weeks by 3 it would be 27 weeks and 3 day is a the official start to the 3rd trimester. Wink
