Where do you keep track? What's your favorite place?

I have a day by day traker called The Pregnancy Journal- I used the same one with my DS and it is fun to compare the two side by side!

I just use the inside cover of my husband's embryology textbook, actually...but I'd love to find something online like what you're talking about! Actually I think the dreaded Babycenter's week by week isn't too bad...

Not so much for tracking, but for taking peeks at developement. I love the zoom feature when you right click.

I have a cute little book called Countdown to a Miracle (http://www.amazon.com/Countdown-Miracle-Making-Me-3rd/dp/0967142830/ref=pd_bbs_sr_1/102-7855223-6864131?ie=UTF8&s=books&qid=1192558384&sr=8-1)

It is a little flip chart - one page for each day of the pregnancy. Every page has a little fact about the baby and in the corner it says how many days you have been pregnant and how many days you have left.

I use the Babycenter's calendar because it is e-mailed to me. ivillage's is alright too.

I like that ticker thing, but I couldn't get mine to come up correctly.
