What’s happening with the baby at 5 weeks pregnant?

Tiny embryo

Deep in your uterus, your baby is now an embryo—a small cluster of cells that is already beginning to form important structures. At this stage, it looks more like a tadpole than a human, but these early developments are crucial for future growth.

Brain and spinal cord development

The baby’s neural tube is starting to form from the ectoderm layer. This tube will eventually develop into the brain, spinal cord, and nerves, which are essential for the baby’s nervous system. The foundation of the nervous system is being laid down, which will later control all body functions.

Heart development

Your baby’s heart and circulatory system are also beginning to form. The heart is still in its early stages, but by the end of this week, it will show signs of early cardiac activity, though it's too small to detect without a specialized ultrasound. This is the beginning of the baby’s cardiovascular system, which will soon supply the rest of the body with oxygen and nutrients.

Formation of other organs

The embryo is also working on the basic building blocks of the lungs, digestive system, and urinary system. These vital organs start to form from the mesoderm (middle layer), while the endoderm (inner layer) begins to create structures like the thyroid, liver, and pancreas.

Growing umbilical cord and placenta

At the same time, the umbilical cord and placenta are developing. These two structures will work together to deliver nutrients, oxygen, and waste removal for your baby throughout the rest of the pregnancy.

How big is your baby at 5 weeks pregnant?

At 5 weeks pregnant, your baby is still very tiny, measuring about the size of a sesame seed—approximately 0.2-0.3 cm long.

How is your belly at 5 weeks pregnant?

At 5 weeks pregnant, your belly likely won’t show any noticeable changes yet. The baby is still very small and deeply embedded in your uterus. You may experience some bloating or mild cramping due to hormonal changes, but it's too early to see any physical signs of pregnancy, like a baby bump.

However, some women may notice their clothes feeling a bit tighter, especially around the waist, due to water retention and hormonal shifts. It's normal if you don't have a visible bump at this stage—your body is still adjusting to the early stages of pregnancy.

Common symptoms and how to manage them?

1) Morning sickness

Morning sickness typically starts around week 5 and can occur at any time of day, not just in the morning. It’s caused by rising pregnancy hormones, particularly human chorionic gonadotropin (hCG), and can lead to nausea and vomiting.

How to manage it:

• Eat small, frequent meals: Keeping your stomach from becoming too empty can help prevent nausea. Try eating bland foods like crackers, toast, or rice.

• Stay hydrated: Dehydration can make nausea worse. Sip water, herbal teas, or ginger ale throughout the day.

• Ginger: Ginger is a natural remedy for nausea. Try ginger tea, ginger candies, or ginger ale with real ginger to soothe your stomach.

• Avoid strong smells: Strong odors can trigger nausea. Try to avoid foods or environments with overpowering smells.

2. Frequent urination

Pregnancy hormones increase blood volume, and your kidneys work harder to filter excess fluid. This leads to more frequent trips to the bathroom, especially in early pregnancy.

How to manage it:

• Stay hydrated: Although you may feel like cutting back on fluids, it’s important to stay hydrated. Just avoid drinking large amounts close to bedtime to reduce nighttime bathroom trips.

• Empty your bladder regularly: Try to empty your bladder completely each time you go to the bathroom to avoid feeling like you need to pee again soon.

3. Tender, swollen breasts

As your body adjusts to pregnancy, hormone levels rise, causing increased blood flow to your breasts, which can lead to soreness, swelling, or tingling.

How to manage it:

• Wear a supportive bra: Choose a soft, supportive bra that offers comfort without adding pressure.

• Avoid tight clothing: Tight-fitting bras or clothes can exacerbate discomfort, so opt for loose, comfortable clothing.

• Apply warm compresses: A warm compress or gentle massage can relieve soreness, but avoid overly hot water that could irritate your skin.

4. Fatigue

Fatigue is a hallmark symptom of early pregnancy. The body is working hard to support the growing embryo, and the increase in progesterone can make you feel exhausted.

How to manage it:

• Rest and sleep: Take naps when possible and get plenty of rest. Try to listen to your body and give yourself permission to slow down.

• Eat balanced meals: Nutrient-dense meals can help give you energy. Keep healthy snacks on hand to avoid energy dips.

• Light exercise: If you feel up to it, gentle activities like walking or yoga can help boost your energy levels.

5. Spotting

Spotting or light bleeding can occur during early pregnancy, especially around week 5. It may be harmless, but it’s important to monitor it.

How to manage it:

• Monitor the bleeding: If the bleeding is light and stops within a day or two, it’s usually normal. However, if it becomes heavier, or you experience severe cramping, contact your healthcare provider immediately.

• Rest and reduce activity: If you're spotting, try to rest and avoid heavy lifting or vigorous activities.

6. Mood swings

Pregnancy hormones, physical changes, and emotional factors can contribute to mood swings during early pregnancy.

How to manage it:

• Talk to someone: Express your feelings to your partner, a friend, or a family member. Emotional support can help you navigate mood swings.

• Practice relaxation techniques: Take time to de-stress with activities like meditation, breathing exercises, or light stretching.

• Rest and eat well: Hormonal shifts and fatigue can make mood swings worse, so make sure you’re getting enough rest and balanced meals.

7. Food cravings or aversions

Hormonal changes can affect your sense of taste and smell, leading to cravings for certain foods or aversions to others.

How to manage it:

• Give in to healthy cravings: If you crave a particular food, try to find a healthy version. For example, if you crave something sweet, opt for fruit instead of candy.

• Avoid strong food odors: If certain smells are unappealing, try to avoid cooking or being around foods that trigger your aversions.

• Eat what you can: If you experience aversions, focus on eating foods that you can tolerate. It’s okay if your diet varies a bit during this time, as long as you're getting essential nutrients.

Frequently asked questions at 5 weeks pregnant

Is it normal to feel so tired at 5 weeks pregnant?

Yes, extreme fatigue is a common symptom during early pregnancy. At 5 weeks, your body is undergoing significant hormonal changes, and the rise in progesterone can make you feel more tired than usual. Rest and proper nutrition can help manage this exhaustion.

What does spotting mean at 5 weeks pregnant?

Spotting during the fifth week of pregnancy is not uncommon and can happen for various reasons, including implantation bleeding. However, while light spotting may be harmless, it’s important to monitor it. If the bleeding is heavier than spotting or accompanied by cramping, contact your healthcare provider to rule out any complications.

What should I expect in terms of morning sickness at 5 weeks?

Morning sickness, or nausea, often begins around week 5. You may experience nausea at any time of the day or night, not just in the morning. Some women experience vomiting, while others just feel queasy. It’s caused by hormonal changes, especially the increase in hCG.

Can I still exercise at 5 weeks pregnant?

Unless your doctor has advised against it, light exercise is generally safe during week 5 of pregnancy. Activities like walking, swimming, or gentle yoga can help you maintain energy and improve circulation. However, it's important to avoid any high-impact or strenuous exercises that could be too taxing on your body.

Is it too early to have an ultrasound at 5 weeks pregnant?

While it’s typically too early to see much on an ultrasound at 5 weeks, some early pregnancy ultrasounds can detect the gestational sac and sometimes the yolk sac. However, a heartbeat may not be visible until about 6 weeks. Most healthcare providers will recommend waiting until week 7 or 8 for the first ultrasound.

Is it safe to have sex at 5 weeks pregnant?

In most cases, sex is safe during early pregnancy, including week 5, as long as there are no complications like bleeding, cramping, or a history of miscarriage. Always check with your healthcare provider if you're unsure or if you experience discomfort.

Is it normal to have tender breasts at 5 weeks pregnant?

Yes, breast tenderness is one of the most common early pregnancy symptoms. The hormonal changes, particularly an increase in estrogen, cause increased blood flow to the breasts, making them feel sore, tender, or swollen. This should subside after the first trimester for most women.

Should I be worried about spotting at 5 weeks pregnant?

Light spotting is common in early pregnancy, but it’s always important to monitor it. If you experience very light spotting, it might just be implantation bleeding. However, if the bleeding is heavier or accompanied by severe cramping, contact your healthcare provider.
