This week's tips
- •Start taking a prenatal vitamin with folic acid if you haven't already—this is crucial for baby's neural development

Looking ahead
In the coming week, the fertilized egg will continue dividing and traveling toward your uterus, where it will implant around week 4. Most pregnancy tests won't detect anything yet, so don't worry if you're not seeing a positive result.
