Your baby
At 9 weeks your baby is about the size of a cherry, and all the major organs, including the heart, brain, lungs, kidneys, and gut, are actively developing. The small embryonic tail has disappeared, and the body is looking more clearly human. Tiny muscles are forming, allowing for the first small spontaneous movements.
Your body
Hormone levels are high, so nausea and fatigue may still be at their peak, along with mood changes and food sensitivities. Your waistline may feel thicker from bloating, and your breasts may continue to grow. Headaches can also show up for some people this week.
This week
Prioritize rest and do not feel guilty about napping or slowing down, since your body is doing extraordinary work. Stay hydrated, which can ease headaches and fatigue. If you have not already, look into prenatal care options and any first trimester screening tests your provider offers.
