I always thought it was because some months have 5 weeks which throws everything off...either way I just count weeks not months even if someone ask how many months I am I always answer it weeks! Lol

@myrandaautumn, See some of them have common sence and math skills.

@jrose114, If they don't want us to include the first or last month (which seems to be the problem). They should write that down somewhere so we can all speak the same math. lol

I don't know why the charts are like that now lol, even my doctor says it's 10 months. he delivered my uncle and my moms four kids lmao

I know right I get so confused all the time now I thought I had it all figured out and then I look at a chart and I'm screwed up all over again.
