Understanding the initial stages of pregnancy is vital for laying a strong foundation for your journey ahead. The preconception stage requires you to pay attention to the basics; the healthier your daily life, the easier it gets for you to get pregnant and transition into the brand-new phase of your life.
Pre-conception is a time of rapid change — for both you and your baby. Every pregnancy is unique, and the information below will help you understand what's happening and how to prepare for the weeks ahead.

Each week brings new things to prepare for. Here's what expecting parents during week 3 typically track in the BabySteps Companion app. Items are sorted by priority so you can focus on what matters most.
Dive into understanding the first trimester of pregnancy.
