Week 7 Pregnancy: Your Baby’s Face Begins to Form

As you enter week 7 of pregnancy, your baby’s growth is progressing quickly, and many essential features are beginning to take shape. This is a dynamic week in foetal development, as your baby’s brain, facial structures, and even limbs start forming. While early pregnancy symptoms may still be present or even intensify, understanding what’s happening can help you feel more connected to the changes taking place in your body.

Wondering about what happened last week? Explore week 6 of pregnancy to learn about key developments like your baby’s first heartbeat and early brain growth, along with changes in your body.

Week 7 body changes

At week 7, your body is adapting in remarkable ways to support your growing baby.

The uterus begins to expand, which may create a subtle sensation of fullness or light pressure in your lower abdomen. To accommodate your baby’s development, blood volume increases, sometimes causing a slightly elevated heart rate as your body works to nourish the placenta.

Hormonal shifts—particularly in hCG, oestrogen, and progesterone—trigger physical changes like breast growth and a thicker uterine lining. Your breasts may feel fuller and more sensitive, preparing for lactation, while increased blood flow often brings a natural “pregnancy glow” to your skin.

Additionally, higher progesterone levels slow down digestion to maximise nutrient absorption, which can sometimes result in bloating or mild discomfort. These adjustments are essential, setting the foundation for a healthy pregnancy.

Week 7 pregnancy symptoms 

Alongside these internal changes, you may feel a range of symptoms. These are often more noticeable and can affect your daily life: 

1. Fatigue

   • Growing the placenta takes a lot of energy, so it’s normal to feel extra tired. 

2. Nausea

   • Nausea, sometimes with vomiting, can happen anytime. This is likely due to high levels of hCG.

3. Frequent urination

   • As your uterus grows, it puts pressure on your bladder, so you may feel the need to pee more often.

4. Breast tenderness

   • Hormonal changes can make your breasts feel tender or sore, similar to what some experience before menstruation

5. Food aversions and cravings

   • Hormonal fluctuations often affect your sense of taste and smell, leading to sudden aversions of certain foods and cravings for others. For example, foods you once enjoyed may become unappealing, while you might crave more unusual items.

6. Bloating and constipation

   • As digestion slows, you might feel bloated or experience constipation. 

7. Mood swings

   • Hormonal shifts may make you feel more emotionally sensitive or reactive. 

8. Heartburn (Acid indigestion or acid reflux)

   • This is due to hormonal changes that relax digestive muscles, allowing stomach acid to flow back into the oesophagus.

Your baby at week 7

At week 7, your baby is growing rapidly, with major developments unfolding. This week, facial features like eyes, nostrils, and ears start to form, giving shape to your baby’s face. Tiny limb buds are also emerging, the beginning stages of arms and legs that will continue to grow and refine over the coming weeks.

Internally, your baby’s brain is developing at a remarkable pace, forming connections that will lay the foundation for complex functions. The heart, now beating regularly, is pumping blood through a newly formed circulatory system, delivering vital nutrients across your baby’s tiny body. Meanwhile, other essential organs, such as the lungs and liver, are beginning to take shape, though they won’t function until after birth.

At this stage, your baby is around the size of a blueberry, approximately 0.5 inches (1.3 cm) long, and though small, these changes are laying a vital foundation for the months to come.

Pregnancy tests & screenings

If you haven’t had a prenatal appointment yet, it’s advisable to schedule an appointment soon. Early screenings and blood tests can offer valuable insights into your pregnancy's progress and provide reassurance as you move forward.

1. Ultrasound

   • An ultrasound at this stage may allow you to see your baby’s heartbeat for the first time. This scan helps confirm gestational age and can detect any early complications, providing an early connection to your little one.

2. Blood tests

   • Blood tests around week 7 typically check hCG levels to track pregnancy progress. Your doctor may also assess your blood type, iron levels, and immunity to certain diseases, such as rubella, to ensure a healthy start.

3. Genetic screening options

   • Depending on your family history or personal factors, your healthcare provider may discuss early genetic screenings. These tests can give insight into potential genetic conditions, helping you make informed choices as your pregnancy progresses.

What to expect at a Week 7 ultrasound?

Your first pregnancy scan around 7 weeks is an important milestone. Here's what you can typically expect:

Why is this scan important?

This early pregnancy scan helps to:

• Confirm your pregnancy
• Check baby's heartbeat
• Estimate your due date
• Ensure the pregnancy is developing in the correct location
• Check if you're carrying one baby or more

What can be seen on the scan?

At this stage of pregnancy, your doctor will usually be able to see:

• A gestational sac containing your growing baby
• A yolk sac that provides early nourishment
• Your tiny embryo (about 5-10mm long)
• Fetal pole (the first visible sign of your developing embryo)
• Heartbeat (your baby's heart rate usually ranges from 90-110 beats per minute at this stage)

How is the ultrasound scan done?

Your doctor will likely perform a transvaginal scan, which provides clearer images since your baby is still very small. This involves gently inserting a small ultrasound probe into the vagina. The procedure is safe and shouldn't be painful, though you may feel mild pressure.

What measurements will be taken?

Your doctor will measure:

• The size of the gestational sac
• The length of your baby from head to bottom (crown-rump length)
• The heart rate

What happens next?

If everything appears normal, your doctor will schedule your next scan, typically between 11-13 weeks. This timing may vary based on your specific situation and your doctor's assessment.

Remember that every pregnancy develops differently. Your doctor will explain the scan findings and address any concerns you may have.

When should you see a doctor to confirm your pregnancy?

Discovering you're pregnant is an exciting moment, but it's essential to know when to seek professional medical care. If you've taken a home pregnancy test and received a positive result, here's guidance on when to consult a doctor:

1. After a positive home test

   • Generally, wait about a week before booking an appointment with a gynaecologist. This allows time for the pregnancy to be visible on an ultrasound scan, typically around 6-7 weeks of gestation.

   • If you have irregular menstrual cycles, consider seeing a doctor sooner to confirm the pregnancy and assess its viability.

2. Immediate medical attention

   • Seek medical care promptly if you experience any unusual symptoms such as vaginal bleeding, severe abdominal pain, or extreme nausea, regardless of how far along you think you are.

Preparing for Week 7 pregnancy

As you approach week 7 of pregnancy, focusing on healthy habits can make a big difference for both you and your baby. Here are some tips to help you feel your best and support your baby’s growth during this important stage: 

1. Prioritise rest and stay hydrated

   • Fatigue is common in early pregnancy, so make rest a priority. Aim to stay well-hydrated throughout the day, as drinking water can help alleviate symptoms like nausea and prevent constipation.

2. Opt for small, frequent meals

   • To manage nausea, try eating smaller, more frequent meals rather than large ones. Bland, easy-to-digest foods such as crackers, toast, and plain rice can be gentle on your stomach. Avoid spicy or greasy foods that may trigger discomfort.

3. Take prenatal vitamins consistently

   • Prenatal vitamins, especially those containing folic acid, are vital for your baby’s neural development. If you haven’t started taking them yet, now is a good time to incorporate them into your routine for added support.

4. Limit caffeine and avoid harmful substances

   • Keep caffeine intake to a maximum of 200 mg per day, about the equivalent of one 12-ounce cup of coffee. It’s also essential to avoid alcohol, smoking, and recreational drugs, as these can negatively impact your baby’s health.

5. Incorporate gentle exercise

   • Light exercise, such as walking or prenatal yoga, can improve circulation, elevate your mood, and reduce stress. These activities can also help prepare your body for the journey ahead.
