What’s happening with the baby at 7 weeks pregnant?

Facial features

At this stage, your baby’s eyes, nose, mouth, and ears are becoming more defined. Though the eyes are still in the early stages, the essential parts for vision—like the cornea, iris, pupil, and retina—are beginning to develop. By the end of this week, these structures will be almost fully formed, and your baby will be able to perceive light by the end of the first trimester. It’s pretty amazing how quickly things are happening!

Limbs

Your baby’s arms and legs are continuing to develop. The arm and leg buds, which are little protrusions that look like paddles, are getting longer. Right now, they don’t look like fully formed limbs yet, but over the next few weeks, they’ll begin to resemble arms and legs more and more.

Brain and nervous system

The neural tube, which will eventually become your baby’s brain and spinal cord, has already formed and closed at both ends by now. The brain itself is dividing into three parts: the forebrain, midbrain, and hindbrain, and it’s a critical period for its development. During this week, your baby is forming an incredible 250,000 brain cells per minute, which is essential for future cognitive function.

Digestive system

Your baby’s digestive system is also developing. The stomach and esophagus (the tube that carries food from the mouth to the stomach) are beginning to form, which is essential for future digestion. Your baby’s liver and pancreas are starting to take shape as well.

Size

Your baby is growing, but still very small—about the size of a blueberry. Though tiny, this is a very important time of rapid growth. It might be hard to believe, but in just a week, your baby has already doubled in size!

Eyelids

At this stage, your baby’s eyelids are beginning to form and partially cover the eyes. However, the eyelids won't open for a while yet. These early developments are laying the foundation for all the sensory functions your baby will need later.

Heart development

While not mentioned in the earlier explanation, your baby’s heart is beating, and by now, it’s dividing into four chambers. It’s amazing to think that the baby’s tiny heart is already pumping blood and circulating nutrients to help them grow.

Growth at a cellular level

Everything is happening at a cellular level too. Cells are rapidly dividing to create the organs and structures needed for survival, and each day brings even more development.

Overall development

Though the baby is still very small, they are already taking shape, and the basics for all major systems—like the nervous system, digestive system, and sensory organs—are getting established. This week marks an important period in your baby’s development that will set the foundation for even more significant changes in the coming weeks.

How big is your baby at 7 weeks pregnant?

At 7 weeks pregnant, your baby is about the size of a blueberry, which is roughly 1.2 cm long. It may seem tiny, but even though it’s small, your baby is growing rapidly and going through major developmental changes. 

How is your belly at 7 weeks pregnant?

At 7 weeks pregnant, your belly likely doesn’t show much of a noticeable bump yet, especially if this is your first pregnancy. Your baby is still very small—about the size of a blueberry—and most of the changes are happening internally.

Common symptoms and how to manage them?

1) Morning sickness (nausea and vomiting)

Morning sickness can occur at any time of day, although it’s most common in the morning. It’s triggered by rising levels of hormones like hCG and estrogen. Nausea may be mild or severe, and it’s often accompanied by vomiting.

How to manage it:

• Eat small, frequent meals.

• Sip ginger tea or munch on ginger candies.

• Stay hydrated with water or clear fluids.

• Consider Vitamin B6 supplements (consult your healthcare provider).

2) Fatigue

Fatigue is a common symptom in early pregnancy due to hormonal shifts, particularly an increase in progesterone. Your body is working harder to support your baby’s growth, which can leave you feeling drained.

How to manage it:

• Take short naps when you can.

• Eat a balanced diet, focusing on protein and whole grains.

• Engage in light exercises, like walking or stretching, to boost energy.

3) Frequent urination

Increased blood flow to your kidneys and the pressure from your growing uterus on your bladder can lead to more frequent urination. This can be one of the earliest signs of pregnancy.

How to manage it:

• Drink plenty of water throughout the day.

• Limit fluid intake before bedtime to reduce nighttime trips.

• Don't hold your urine too long to avoid discomfort.

4) Mood swings

Hormonal changes during pregnancy can affect your emotions, leading to mood swings. You may feel elated one moment and irritable or tearful the next, which is entirely normal during this time.

How to manage it:

• Practice relaxation techniques like deep breathing or meditation.

• Ensure you get enough rest and manage stress.

• Talk to your partner or support system when you’re feeling overwhelmed.

5) Food aversions and cravings

Hormonal fluctuations can alter your sense of taste and smell, making certain foods unappealing while sparking cravings for others. These changes are usually temporary but can be intense in early pregnancy.

How to manage it:

• Eat what feels right to you, even in smaller portions.

• Focus on healthy, nutrient-rich foods when possible.

• Stay flexible and listen to your body’s needs.

6) Bloating

Bloating occurs because of hormonal changes that slow down your digestion, causing a feeling of fullness or tightness in your stomach. It’s a common early pregnancy symptom and can make your belly feel puffier.

How to manage it:

• Avoid gas-producing foods like beans, cabbage, and carbonated drinks.

• Eat smaller meals throughout the day.

• Try light physical activity, such as walking, to relieve discomfort.

7) Breast tenderness

As your body prepares for breastfeeding, your breasts may become tender, swollen, or more sensitive due to hormonal changes. This is a typical early pregnancy symptom.

How to manage it:

• Wear a supportive, comfortable bra.

• Use warm compresses or take warm showers for relief.

• Consider gentle breast massage to ease soreness.

8) Increased saliva

Some women experience an increase in saliva production during pregnancy, which can lead to a constant feeling of having too much saliva in the mouth.

How to manage it:

• Carry tissues or mints with you to manage excess saliva.

• Sip small amounts of water throughout the day to stay hydrated.

• Avoid strong-smelling foods that might make it worse.

Frequently asked questions at 7 weeks pregnant

Is it normal to have cramps at 7 weeks pregnant?

Mild cramps are common in early pregnancy as your uterus begins to stretch and grow. However, if you experience severe cramping, heavy bleeding, or sharp pains, it's important to contact your healthcare provider.

Can I have a miscarriage at 7 weeks pregnant?

While the risk of miscarriage decreases with time, it is still possible, particularly during the early weeks. If you're experiencing heavy bleeding, cramping, or passing tissue, reach out to your doctor for advice and support.

What foods should I avoid at 7 weeks pregnant?

At 7 weeks, it’s important to avoid foods that can harm your baby, such as:

• Swordfish, shark, or other high-mercury fish.

• Raw or undercooked meats (including sushi and deli meats).

• Unpasteurized dairy products like soft cheeses (e.g., queso fresco).

• Raw eggs or homemade cookie dough.

• Unwashed vegetables like bean sprouts.

What should I expect during my first ultrasound at 7 weeks?

At 7 weeks, your doctor may perform a transvaginal ultrasound to confirm the pregnancy, check the baby’s heartbeat, and measure the baby’s growth. It’s too early for a detailed image of the baby, but the heartbeat may be visible.

Is it safe to exercise at 7 weeks pregnant?

Mild to moderate exercise is generally safe during early pregnancy, unless advised otherwise by your healthcare provider. Walking, swimming, and prenatal yoga can be great options. Avoid high-risk activities or exercises that could lead to a fall or injury.

Can I travel during pregnancy at 7 weeks?

Yes, it's usually safe to travel during the early stages of pregnancy, but always check with your doctor first, especially if you have complications or are feeling unwell. Keep in mind that morning sickness and fatigue may make travel uncomfortable.

When should I tell people I'm pregnant?

The decision of when to share your pregnancy news is personal. Some people wait until after the first trimester when the risk of miscarriage decreases. Others share earlier with close friends and family. Choose what feels right for you.

Why do I feel bloated at 7 weeks pregnant?

Hormonal changes during early pregnancy, especially increased progesterone, can slow digestion and cause bloating. This is a normal symptom and usually improves as your body adjusts.

What should I do if I miss my prenatal vitamins?

If you forget to take your prenatal vitamin, take it as soon as you remember. If you’re close to the next dose, skip the missed one and continue with your regular schedule. Consistency is key for proper nutrition, but missing one dose is usually not harmful.
