Any good "week by week" email subscriptions?

In my last pregnancy, I signed up for those weekly emails - showing the baby's development and some Q&A pegged to your due date - from babycenter.com.

Which ones do you use? Any less annoying than others? And dare I ask.... any natural birth or AP friendly? (I know, I know... a gal can dream!)

I don't recall minding babycenter's actually (though I was much more mainstream before I had children), just wanted to see what else is out there. TIA!
