What week is considered third trimester

@Chloe thank you 💜

Depends on who your asking or what pregnancy tracker you use. With my daughter one told me I was in my 3rd trimester at 27 the other said 28w was 3rd trimester so I went with the one that was on track with where I was gestationally (one tracker was a day behind lol) but the one that was on was on track and 27w was 3rd trimester

28

Im 27weeks today and ive been told 28 weeks is the start of the third trimester

I think of every trimester as 3 months long, 12 weeks are in 3 months so 28 weeks I would say is the third trimester

I went to my OB at 25 weeks for my appointment he said I’m already in the third trimester because baby could come as early as 11 more weeks
