It really Is confusing, there's so many ways people calculate this, but I juss go by 4 weeks= 1 month so therefore It would be 28 weeks.
I kno right so confusing!!!
I always just devide my weeks by 4 and come up with the months. All this weeks and stuff confuses me. I have the book what to expect when u r expecting and it said i was in my 7th month even before my calculations so idk. Like i am 31 weeks now so i would say i am a week from being 8 months and that would be putting me at having baby at the end of 9th month which i guess they figure u r preg for a full nine months not habing baby at begining of 9th month idk lol
28 weeks !! But I've also heard 27 weeks depends on if your goin by 9 or 10 months !!
