Babycenter and I'm pregnant app
Oh yeah and the other pregnancy app I use is......Health and parenting (pregnancy).
I know some awesome web sites....Baby Center, Cafe Mom and The Bump. They also have question forum's, advice forums and other friendly forum's!!!!
Ovia pregnancy is awesome! It gives you little tidbits daily, as well as some other cool features :)
I also use the babycenter pregnancy app. It gives good tips and articles, but I still don't like it as much as this one.
