7 Weeks Pregnant: Your Baby Has Eyes and Ears

Week 7 marks a significant period in your pregnancy journey. As you approach the end of the first trimester, both you and your baby undergo remarkable changes. This week is crucial for your baby's development and brings about various physical and emotional changes for you.

Your Baby's Development at 7 Weeks

Size and Growth

At 7 weeks, the embryo is as big as a blueberry, measuring approximately 10mm from the top of the head to the bottom. This measurement is called the crown-rump length. Although tiny, this week is pivotal for your baby's growth.

Development of the Organs, Systems and Limbs

The baby's brain and face are rapidly developing. Tiny nostrils become visible, and the eye lenses start forming. The brain grows and develops very quickly at this stage, making the head look very over-sized in comparison to the body. Your baby's eyes and ears are also continuing to form. Although the outer ears are not yet visible, the inner ears are starting to develop.

Cartilage is forming on the limb buds, which will eventually become the bones of the legs and arms. The ends of the arm buds flatten out to resemble paddles; these will eventually form into your baby's hands.

Nerve cells are multiplying and developing, and along with the developing brain, will become the nervous system.


One of the most exciting developments this week is the baby's heartbeat. With a heart rate about twice as fast as yours, it's sometimes possible to see it on an ultrasound.

Your Body at Week 7

Physical Changes

At 7 weeks pregnant, your uterus is now the size of a lemon. You might notice physical changes in your body. Although it's early for a pronounced baby bump, you might feel bloating.

Hormonal Changes

The increase in pregnancy hormones like hCG and progesterone significantly impacts your body. These hormones are crucial for sustaining the pregnancy but can also cause noticeable symptoms.

Pregnancy Symptoms at Week 7

  1. Nausea and Morning Sickness

    Morning sickness is a common symptom around this week. Despite its name, nausea can occur at any time of the day, and is one of the more unpleasant pregnancy symptoms to have to deal with.


    Increased levels of progesterone can make you feel unusually tired. Your body is also working hard to support the growing embryo, contributing to this fatigue.

    Breast Changes

    Your breasts might feel tender and swollen due to hormonal changes, preparing your body for breastfeeding.

    Food Aversions and Cravings

    Many women experience a change in their sense of taste and smell, leading to specific food aversions or cravings.

    Frequent Urination

    The growing uterus starts to put pressure on your bladder, leading to more frequent trips to the bathroom.

    Emotional Changes

    Fluctuating hormones can also impact your emotions, leading to mood swings.

Managing Symptoms at Week 7

Diet and Hydration

Eating small, frequent meals can help manage nausea. Staying hydrated is also essential.


Ensure you get plenty of rest. Listen to your body and rest when you feel tired.

Prenatal Care

Regular prenatal visits are crucial. Discuss any concerns with your healthcare provider.

Emotional Support

Seek support from loved ones or a professional if you're struggling emotionally.


Week 7 is a week of significant developments and changes. While it can be challenging, understanding what to expect and how to manage symptoms can help you navigate this week with more ease. Remember, every pregnancy is unique, so it's essential to consult with your healthcare provider for personalised advice.
