Pregnancy Week 9

(10 minute read)

How Big is Baby at 9 Weeks?

As you enter the 9th week of pregnancy, your baby, often referred to as a fetus at this stage, undergoes significant development. At 9 weeks, the fetus is approximately the size of a cherry, measuring about 2.3 cm long from head to bottom. Despite its small size, your baby is growing very quickly and developing essential body systems and structures.

Facial features are developing rapidly. Your baby's eyes have become larger, and they have a bit of colour to them. There is a mouth and tongue which even contains some tiny taste buds.

Your baby's hands and feet are still forming; although the fingers and toes have not yet separated out, there are ridges which define where they will be. The internal organs are still developing.

Your Body at Week 9

During the 9th week of pregnancy, your body continues to undergo a myriad of changes to accommodate the growing fetus. One of the most noticeable changes is the expansion of the uterus. Although it might not be visibly noticeable to others, you might start feeling that your clothes are getting snugger around your waist.

Hormonal changes are in full swing, with increased levels of hormones like human chorionic gonadotropin (hCG), progesterone, and estrogen. These hormonal changes are crucial for supporting the pregnancy but can lead to various symptoms, such as emotional fluctuations. One minute you will be sad and the next blissfully happy. This is perfectly normal and nothing to worry about.

Pregnancy Symptoms at Week 9

  1. Morning Sickness: Nausea and vomiting, commonly known as morning sickness, are prevalent symptoms at this stage. Despite its name, morning sickness can occur at any time of the day or night. Eating small, frequent meals and avoiding triggers like strong smells can help manage this symptom.
  2. Fatigue: Increased fatigue is another common symptom during the 9th week. The high levels of progesterone, along with the metabolic changes happening in your body, contribute to this exhaustion. Prioritising rest and maintaining a healthy diet can help you manage fatigue.
  3. Breast Changes: You might notice your breasts are becoming larger, more tender, and sensitive due to the hormonal changes. It is a good idea at this stage to start wearing a supportive bra.
  4. Frequent Urination: As the uterus expands, it starts to exert pressure on your bladder, resulting in the need to urinate more often.
  5. Mood Swings: The fluctuation of hormones can also affect your emotions, leading to mood swings. It's normal to feel a spectrum of emotions during this time. However, if you find these mood swings overwhelming, it's essential to talk to your healthcare provider.
  6. Increased Vaginal Discharge: An increase in vaginal discharge, which is usually thin and white, is normal during pregnancy. This is your body's way of preventing infections.
  7. Food Cravings or Aversions: You might start noticing specific cravings or aversions to certain foods. It's important to maintain a balanced diet, even if your preferences change.
  8. Nasal Congestion: Increased blood flow and hormonal changes can lead to swelling of the mucous membranes in your nose, causing congestion.

Tips for Managing Symptoms and Maintaining Health

    • Stay Hydrated: Drinking plenty of fluids is crucial, especially if you're experiencing morning sickness or increased urination.
    • Nutrition: Focus on a balanced diet rich in fruits, vegetables, lean proteins, and whole grains. Prenatal vitamins can help fill any nutritional gaps.
    • Rest and Relaxation: Ensure you're getting enough rest. Light exercise like walking or prenatal yoga can be beneficial, but always consult your healthcare provider before starting any new exercise regime.
    • Regular Check-ups: Continue with your regular prenatal check-ups. These appointments are essential for monitoring your health and the baby's development.


    Week 9 is a time of rapid growth and development for your baby and significant changes for you. Understanding these changes and knowing how to manage the symptoms can help make this period more comfortable. Remember, every pregnancy is unique, so it's crucial to stay in close contact with your healthcare provider for personalised advice and support.
