I saw this website in another month's group:
It tells you how many days you have left until until you EDD, as well as how many weeks and days you are.
Today I am 26 weeks and 2 days, and have 96 days left! (I'm guessing I'll go over though, as my midwife says most first time mom's do).
Still, to think I have less than 100 days to go...WOW!
