You this week

This week's tips
- •Consider scheduling your anatomy ultrasound if you haven't already—this is typically done between weeks 18-22 and is something many families look forward to
- •Invest in comfortable, well-fitting maternity clothes if you haven't already; proper support can ease back discomfort
- •Start thinking about screening tests; discuss options with your healthcare provider, including the quad screen or non-invasive prenatal testing (NIPT)
- •Practice good posture to prevent backaches as your center of gravity shifts
- •Stay hydrated and include fiber in your diet to manage constipation
- •Use fragrance-free products if you're experiencing sensitive skin or the pregnancy mask
