Week 1: Baby at Week 1

This week marks the approximate day of your last menstrual cycle (LMP). It's important to understand that technically, you're not yet pregnant this week! Week 1 is calculated from the first day of your LMP, and this date is used to estimate your due date later on. Think of it as the starting point for tracking your pregnancy journey. While there's no baby yet, your body is preparing for the potential for pregnancy. Hormones are at work, and the lining of your uterus is getting ready to support a fertilized egg, should conception occur. This week is all about preparing the groundwork for the incredible journey ahead. The journey from conception to birth is a complex and miraculous one. The fertilized egg, if conception occurs, will travel down the fallopian tube and implant in the uterus.
