I think it's like 13 weeks 3 days starts the second trimester and 26w6d starts the second. I get confused with the months. Like I'm 14 weeks and I think I'm technically 3 months and in my fourth month? or I'm 4 months? I have no clue. it's all a big ball of confusion.

makes sense, technically 13 weeks starts the second tri is what my ob said bc it's the start of month 4@mam426

@brinleysmommy, there some months that have 5 weeks and that's why it's goofy

that first chart you posted is way wrong your not In the 3 month for 13-17

3 months is 12 when you divide it by 4 not 13.@mam426,

here are many forms and they all look the same. I would like to see one from a doc if someone has one

I know some months do have five weeks in them so maybe that's why? I think it's every five or six months there's a month with 5 weeks.

I'm not the one day by its wrong. others are and it's irritating and confusing me.@mam426,

same as this one but wjy di rd month 3 & 9 have 5 weeks.@katarama,

@brinleysmommy, if you Google all the charts I am finding is the same as this one.

@taylay531, @katarama , that's what I thought but some are telliny others its wrong.

well apartantly its counting wrong as I've been told. there are 5 weeks in 3 months and 5 in 40 which wouldn't be right I'm guessing.@kparis, @mam426

This one is accurate.

This matches the chart my doctor gave me- it is accurate!

I showed this to my doc last appt and he said this chart is accurate. so I will stick with this chart.

This is the one I've been going by too
