Baby Development

What's happening inside the womb this week

Week 12 is part of early organ formation. Your baby's brain, spinal cord, and heart development continue quickly. Tiny facial structures and limb buds become more defined, and circulation becomes stronger each week.

By this stage, foundational systems are being built. Although your bump may still be small, inside the uterus development is rapid and highly sensitive to nutrition, hydration, and rest.

Your Body This Week

Physical and emotional changes you may experience

Hormonal changes in week 12 may cause nausea, breast tenderness, fatigue, mood shifts, and bloating. Frequent urination can increase as blood flow and kidney activity rise.

Focus on gentle routines, short rest breaks, and hydration. If vomiting is severe, you cannot keep fluids down, or pain/bleeding occurs, contact your doctor promptly.
