When is third trimester

[babyboo2013]

I'm so confused.  Always thought 27 weeks is when third trimester starts but the hospital I'm delivering at says 25 weeks, others say 27 weeks and 28 weeks. I'm 25 weeks now so I don't exactly know when I'm in third trimester. What are others moms told.

Third trimester starts at 26 weeks dear...so if U at 27 weeks den dat means yr 3rd trimester has begun a week ago....

3rd trimester starts at week 27. Baby is considered full term at 37 weeks.

It varies depending on who uou ask, but in general it's around 27 weeks.

I was told with both my pregnancies week 27 is the start of 7month as well as the start of 3rd trimester.
I was confused with my hospital yesterday as I was always told week 37 was full term, as in there bathroom a poster said 39W was full term......
But Ive always been told that at 36W your baby can come anyday but there lungs are not fully developed till 37W. ?
Its confusing. I hate that there switching everywhere around
