  • You're a third of the way done with your 40 weeks of pregnancy.

  • Some people divide the 40 weeks by 3.  Some go by 13 weeks.  Some go by 12.  I'll go by whatever my OB says and you should too! :)
  • Ahh I see. I've never thought of it that way.

    My midwife has always said day 1 of 13 weeks starts the 2nd trimester. Day 1 of 28 weeks starts the 3rd. Its what I've always gone by as well, and I think I'll stick to it. ;)

  • Simple division my dear Wink

    Which is obvious now.. I had just never heard of people looking at it that way. I know some say 12, some say 13, and some even say 14.. but I'd never heard of people doing it this way.

  • Some people go by that. But my doctor says 1st day of 13th week is second tri, so that's what I go by. As far as I'm concerned I'm in my second trimester. But on here everyone seems to go 13 weeks 3 days, so I won't dare post on second tri until then.

    Just clarifying - first day of the 13th week (so 12wks 1day) or 13 wks 1 day?

  • Its just a bump thing.  I don't think any doctors go by that at all.  Even though the division makes sense, that is not how trimesters are actually classified.
