9 months = 40 weeks??

I realize that some months have more days and other months have fewer days. I get that. On average, I'd assume that most months include about 4.33 weeks, so what's up with the whole pregnancy being 40 weeks?!?!

I did a little reading up on the subject and apparently the calculation is actually something like 4.445 weeks in a month. I would guess that's so the first 2 weeks that you're not really pregnant get averaged into the whole 9 months. I don't know. Bottom line, a pregnancy lasts 260 days from the date of conception and 280 days from the date of your last cycle.

Sooooo......my second trimester started on December 10th, 2010, and my third trimester started on March 26th, 2011. I'm now 7 months pregnant, I'm in my third trimester, and I'm 70% through my pregnancy! Holy cow! Honestly, the 40 week thing still throws me off a little since I still have 12 weeks left, but I'm trying to stay positive, especially since I read that I'll likely gain another 10 pounds. Ahhhh! I'm going to need a serious workout buddy after all of this!

Here's a couple of belly pix -- they are a little fuzzy because I took them by myself and the light wasn't very good...also I'm vertically challenged with a short torso, etc. etc. haha...
