how to count when turn the next month in preganancy

[trena33]

a little confussed when do i turn the next month in my pregnancy?

[ummmm]

It's better to do it by weeks....as you're pregnant for (app) 40 weeks and not nine months.

Anyway....when I was 16 weeks....I said four months.

it's 40 weeks from day 1, which is more or less 9 months. if your day 1 is the 9th of the month, every 9th will be another month.

in early stages i work on 4 weeks is 1 month.
towards the end i count back so if due 27th July youre 6 months pregnant today.

But most women do use the weeks system, same as midwives
