Zero to Forty is a week-by-week guide to the miracle of pregnancy and all the various indignities that come with it. The calendar follows the forty-week model.

The column is well-researched but not written by a health care professional. Consider it your internet BFF pregnancy guide. See our legal disclaimer below.

The follow-up to our pregnancy calendar is Bounce Back, which is about the postpartum experience -- the good, the bad and the gory. There Amalah covers everything that happens to your body, mind and circadian rhythms after you have a baby, and (hopefully) helps you make sense of the New Normal. You must go read that too!

Our Pregnancy Calendar, Zero to Forty, was written by Amy Corbett Storch while she was pregnant with her second son, Ezra.

Amy, also known as Amalah, writes the Advice Smackdown and Bounce Back here at Alpha Mom. You can follow her daily mothering adventures at her own site, www.Amalah.com.

The Zero to Forty illustrations were created by the artist Brenda Ponnay aka Secret Agent Josephine. Brenda is very talented and these images are copyright-protected. You should hire her if you want your own unique ones!
