I have a question I'm 17wks today . does this means I'm 5 months or is it 4 1/2 months?

4 1-2 I believe cause I'm sure 20 weeks is 5 months :)

I use this

I jus divide how many weeks I am by 4 and then it tells me the months ..

@firstbabyy, I use a chart similar to that one, a lot more accurate than counting each month as 4 weeks, because all months are longer than 4 exact week
