Your baby is the size of a cherry

Baby Development
Your baby's arms are growing longer, and the elbows are now functional. The toes are visible, and the eyelids have formed and are now fused shut over the eyes, where they will remain for several more months to protect the developing optics. The head is still very large in proportion to the body, but the chin is becoming more defined.
Muscles are developing, and the fetus is capable of making small, spontaneous movements, like tiny twitches and stretches. While you can't feel these movements yet, they are a sign that the nervous system is starting to communicate with the muscles. The beginnings of teeth and taste buds are also forming.
Your Body This Week
Profound fatigue is a hallmark of this stage, as the placenta is working hard to establish itself as the primary source of hormones and nutrients for the fetus. Your sense of smell may be at its peak, making you extremely sensitive to certain odors and potentially worsening any nausea you're experiencing.
Your heart rate has likely increased to handle the extra blood volume, and you may feel your heart pounding at times. Hormonal fluctuations continue to influence your mood, and it's normal to feel a mix of excitement, anxiety, and everything in between.

During week 9 of your pregnancy, it's common to experience tender, enlarged breasts, thanks to the hormones like estrogen and progesterone gearing up your body for nourishing your baby post-birth. As you navigate these early weeks, recognize that significant weight gain isn't expected yet—your body's primary focus is on ensuring an efficient nutrient supply to your developing baby without the need for extra calories during the first trimester. It's important to prioritize nutrient-dense foods rather than quantity; aim to fill your diet with fruits, vegetables, whole grains, and lean proteins. Small, frequent meals can help manage nausea and maintain energy levels, and incorporating ginger into your diet may help with any morning sickness you might be experiencing. Remember, adequate hydration through water is essential and can also help ease constipation. Staying active with moderate exercise like walking or prenatal yoga is beneficial, but be sure to rest when needed. Despite any lack of symptoms, prioritize early prenatal care to monitor your baby's development. Your body is working hard behind the scenes, gradually adjusting to support your little one's growth, even if these changes aren't always obvious or physically evident at this stage.
