The app I found says the same thing. I just go by the weeks now even though the months sound cooler to me lol.
They consider 20weeks is 5months.. Half way point in pregnancy considering full term is 40 weeks which is 10months
http://www.baby2see.com/pregnancylength.html. this is the chart I have been going by. Every site has something different maybe I will Google NIH's definition the government must know right?? :-)
That doesn't make sense... unless they are going by conception date... which most dont. Doctor s usually go by the first day of your last menstrual and if they change it then it's started 2weeks before conception. Basically ovulation is the start of pregnancy. So
weeks 1-4 are month 0
Weeks 5-8 are month 1
Weeks 9-12 are month 2
weeks 13-16 are month 3
weeks 17-20 are month 4
weeks 21-24 are month 5
weeks 25-28 are month 6
weeks 29-32 are month 7
weeks 33-36 are month 8
weeks 36-40 are month 9
I hope that helped you.
Well twosacharm I googled and found mmmm about 4 different calculations. NIH only does the trimesters. My book from my insurance company has a whole other calculation. This is fun... im definitely still sticking to weeks until I am a 9 months... then I.ll just say ready to pop when asked how far I am lol.
Chelley5 thank u because when I add 18 weeks its 4 mnths, makes sense, at kprince2 i Lol like ur theory,I'm going with that too lol cuz this too much confusion for me lol
