at what week does 8 months start?

32?

I've been going by this chart. It could be wrong though.

take your weeks that you are and divide it by 4.4, that will give you your months! :)

I'm 31 weeks and just hitting 7 months. My 9 mth old will be 10 mths on Monday, and I'm due on his birthday April 8.
