well i am 27 weeks today (hurrah!) and my pregnancy book - What to expect when you are expecting says that i am still in the second trimester until week 28.
However, I received an email from babycentre to say that i am now in my last trimester at week 27.

does anyone know which is correct?

We had this discussion in the Feb forum the other day and we all had different answers ranging from 26 weeks to 29 weeks! Sorry, not much help I know! :\)

i thought it was from week 28 when the 3rd trimester started :\?

the logic im using is if you divide 40 by 3 to get each trimester then x it by 2 to get when the 3rd trimester starts and thats 26.6666666 weeks.
so that means roughly about 26+4 if you want to be really picky

27 weeks, as I'm currently 26 weeks and all the email updates I get have been saying "you're in the last week of the 2nd trimester" xx
