Week-by-Week Pregnancy Guide

Every week of pregnancy brings something new — a heartbeat, a first kick, fingernails, eyelashes, a face that's becoming unmistakably yours. This guide walks you through all 40 weeks, from implantation to the moment you finally meet them.

Each week covers fetal development, what's changing in your body, symptoms to expect, and what to talk to your provider about. Evidence-based, plainly written, and actually useful at 2am.
