Baby Center Canada or Baby Centre
I was happy to discover that Baby Center has started a Canadian version of their site. While I was pregnant I used their UK site.
The Baby Center lets you put in your due date or babies birthday and they send you weekly updates about the stage in the pregnancy or the developmental stage your baby is at. They also have advice and support for those trying to get pregnant.
As well they have a forum so you can “meet up” with other Mom’s and Mom’s to be.
