When does the third trimester start?

Question

I’ve seen so many different things! I’m 27 weeks today

Answer

Each trimester is 13.3 weeks long, so 3rd trimester should start at 26 weeks 6 days. Otherwise, some trimesters are longer than others 🤷‍♀️ At least, this is how my OB explained it to me.
