I am currently 23 weeks and 2 days. All along I tought I was 5 months going on 6 months (on my 24th week) but I found this site

http://www.baby2see.com/pregnancylength.html

that actually says I have been in my 6th month. So I have been telling people that ask the wrong info all along!

it doesnt make sense to me, but is that site correct? Are there any other calendars you use have found that break down the weeks and months?
