I never go by the whole 9 month thing, I don't even know why people refer to pregnancy as 9 months when it's really 10.
In my opinion at 32 wks is 8 months. . I go by mayo clinic pregnancy books. . ((:
The first trimester is the first 3 months then second trimester is the 4th 5th and 6th months and then the 3rd trimester is the 7th 8th and 9th month
Here is a link to the website my OB told me to go by...
