Looking for a pregnancy calendar or countdown software.. please read??

I am looking for a pregnancy calendar or pregnancy countdown software online that is really detailed on the development of the baby from week to week. I also would like it to give other information like what should I be feeling, etc. I have looked up pregnancy calendars, etc on google, but I haven’t come across anything really good. I want something that will be fun for me to look at each day or each week during my pregnancy! Any ideas???

go to whattoexpect.com thats were i registered and they give a week by week of your body, feelings and the babys development it also has a weight gain tracker and journal you can print off and shopping check lists for things like clothes,crib, diapers that kind of thing its great the book is good too!!!!!!!!!!!!!!
