4th Month Pregnancy: Symptoms, Baby Development & What to Expect

The 4th month pregnancy marks the beginning of an exciting new phase. As you enter the second trimester, many of the uncomfortable symptoms of early pregnancy may start to ease, and you may finally begin feeling more energetic. Your growing baby is becoming more active, developing stronger muscles, facial expressions, and tiny fingerprints while your baby bump gradually becomes more noticeable.

During pregnancy weeks 13 to 16, your baby's organs continue maturing, bones become stronger, and the placenta takes over many of the important functions needed to support your baby's growth. Although every pregnancy is different, this month often feels more comfortable for many expectant mothers.

According to the Centers for Disease Control and Prevention (CDC), continuing prenatal care, eating a balanced diet, and taking daily prenatal vitamins with folic acid remain essential throughout pregnancy to support healthy fetal development.

In this complete guide, you'll learn everything about 4th month pregnancy symptoms, baby development in the 4th month of pregnancy, body changes, pregnancy care, diet, precautions, healthy habits, and what to expect as you move further into your second trimester.

Round Ligament Pain	Stretching ligaments support the growing uterus
Increased Appetite	Baby's rapid growth increases nutritional needs

First Baby Movements (Quickening)	Baby becomes more active inside the womb

Let's discuss these 4th month pregnancy symptoms in detail.

---

1. Increased Energy During the 4th Month Pregnancy

One of the biggest changes during the 4th month of pregnancy is that many women begin feeling less tired. As hormone levels stabilize, you may notice improved energy, better sleep, and an overall sense of well-being.

Even though you feel better, your body is still working hard to support your growing baby. Continue getting enough sleep, eating nutritious meals, and staying hydrated.

---

2. Growing Baby Bump at 4 Months Pregnant

By the 4th month of pregnancy, your uterus has grown above the pelvic bone, making your baby bump more noticeable.

Some women begin wearing maternity clothes around this stage, while others may still have a smaller bump. Every pregnancy develops differently, so the size of your bump doesn't always reflect your baby's growth.

---

3. Round Ligament Pain During the Fourth Month Pregnancy

As your uterus expands, the ligaments supporting it stretch, causing brief sharp or pulling pain on one or both sides of your lower abdomen.

Round ligament pain usually lasts only a few seconds and often occurs when changing positions, standing up quickly, coughing, or laughing.

---

4. Increased Appetite During 4th Month Pregnancy

Many women notice that their appetite returns after the first trimester. As morning sickness improves, your body naturally needs more nutrients to support baby development in the 4th month of pregnancy.

Choose nutrient-rich meals instead of simply eating larger portions. Protein, fruits, vegetables, whole grains, dairy products, and healthy fats provide essential nutrients for your growing baby.

---

5. Mild Back Pain at 4 Months Pregnant

As your abdomen grows, your posture changes and your lower back works harder to support your body's changing center of gravity.

Wearing supportive footwear, maintaining good posture, and performing gentle prenatal stretches may help relieve mild back discomfort.

---

6. Breast Changes During the 4th Month of Pregnancy

Your breasts continue preparing for breastfeeding throughout the 4th month pregnancy.

You may notice:

• Fuller breasts

• Darker nipples

• More visible veins

• Increased sensitivity

• Occasional leakage of colostrum later in pregnancy

A well-fitting supportive bra can improve comfort during this stage.

---

7. Nasal Congestion During the 4th Month of Pregnancy

Increased blood flow and pregnancy hormones can cause swelling inside the nasal passages, leading to a stuffy nose. Staying hydrated, using a humidifier, or a saline nasal spray (if approved by your healthcare provider) may help relieve congestion. 

---

8. Heartburn During the 4th Month Pregnancy

Pregnancy hormones relax the valve between your stomach and esophagus, allowing stomach acid to move upward.

Heartburn becomes more common as your uterus grows and places additional pressure on your stomach.

Eating smaller meals, avoiding spicy foods, and not lying down immediately after eating may help reduce discomfort.

---

9. Constipation During the Fourth Month of Pregnancy

Progesterone slows digestion, making constipation a common symptom throughout pregnancy.

To support healthy digestion:

• Eat high-fiber foods

• Drink plenty of water

• Stay physically active

• Include fruits and vegetables in your daily diet

Speak with your healthcare provider before taking any laxatives.

---

10. Nasal Congestion During Pregnancy

Many women experience a stuffy nose during the 4th month of pregnancy because increased blood flow causes swelling inside the nasal passages.

Using a humidifier, staying hydrated, and saline nasal sprays approved by your healthcare provider may help relieve symptoms.

---

11. Skin Changes During the 4th Month Pregnancy

Pregnancy hormones can cause noticeable skin changes during the second trimester.

You may notice:

• Darkening of the nipples

• A dark line called the linea nigra

• Mild pigmentation on the face (melasma)

• A healthy pregnancy glow due to increased blood circulation

These changes are usually temporary and often fade after delivery.

Can You Feel Baby Movement in the 4th Month?

Yes, some women begin feeling baby movements during the 4th month of pregnancy, especially between weeks 16 and 20. These first movements, known as quickening, often feel like gentle flutters, bubbles, or tiny taps inside the abdomen.

First-time mothers may notice these movements slightly later, while women who have been pregnant before may recognize them earlier.

---

💡 Did You Know?

One of the most exciting milestones of the 4th month of pregnancy is that your baby begins making facial expressions, sucking movements, and active kicks—even if you can't feel all of them yet. Tiny fingerprints are also forming during this stage, making your baby's fingerprints unique for life.

Emotional Changes During the Fourth Month of Pregnancy

The 4th month of pregnancy often brings greater emotional stability, although excitement, anxiety, and mood changes are still completely normal as your pregnancy progresses.

As you enter the second trimester, many women begin feeling more confident because the risk of miscarriage has significantly decreased and early pregnancy symptoms often improve. At the same time, preparing for parenthood and watching your body change can bring a wide range of emotions.

You may experience:

• Excitement about your growing baby

• Relief as nausea begins improving

• Increased confidence after entering the second trimester

• Anxiety before prenatal checkups or anatomy scans

• Mood swings caused by ongoing hormonal changes

• Growing emotional attachment to your baby

• Curiosity about feeling your baby's first movements

• Occasional worries about labor, parenting, or your baby's health

These emotional changes are a natural part of the fourth month pregnancy journey. Talking openly with your partner, family members, trusted friends, or healthcare provider can provide reassurance and emotional support throughout this exciting stage.

What Happens During the 4th Month of Pregnancy?

During the 4th month of pregnancy, your baby grows rapidly, major organs continue maturing, and your body enters the more comfortable second trimester. Your baby bump becomes more visible, and you may even feel your baby's first movements.

The 4th month of pregnancy is an exciting milestone because it marks the beginning of the second trimester, often called the "honeymoon phase" of pregnancy. Between pregnancy weeks 13 to 16, your baby's body becomes more proportionate, bones become stronger, facial muscles develop, and tiny movements become more coordinated.

At the same time, your body continues adapting to support your growing baby. The placenta is now fully functioning, delivering oxygen and nutrients while removing waste products. Many women notice that morning sickness and extreme fatigue begin to improve, allowing them to enjoy pregnancy more comfortably.

---

Changes in the Mother's Body During the 4th Month of Pregnancy

Your body changes noticeably during the 4th month of pregnancy as the uterus grows, hormones stabilize, and your baby bump becomes more visible.

Although every pregnancy is unique, several physical changes are common during this stage.

You may notice:

• A visible baby bump

• Increased appetite

• Reduced morning sickness

• Higher energy levels

• Mild back pain

• Round ligament pain

• Breast enlargement

• Increased vaginal discharge

• Darkening of the skin (linea nigra or melasma)

• Occasional headaches or dizziness

• Feeling your baby's first fluttering movements (quickening)

By the end of the 4th month pregnancy, your uterus is about the size of a melon and has risen well above the pelvic bone. As your abdomen expands, your center of gravity shifts, making good posture and supportive footwear increasingly important.

Weight gain also becomes more noticeable during this month. Most women gain around 1 to 2 pounds (0.5–1 kg) per week during the second trimester, although healthy weight gain depends on your pre-pregnancy BMI and your healthcare provider's recommendations.

---

Changes in Your Growing Baby During the 4th Month of Pregnancy

Baby development in the 4th month of pregnancy becomes more remarkable as bones strengthen, facial expressions appear, muscles grow stronger, and the baby becomes much more active inside the womb.

Between pregnancy weeks 13 and 16, your baby experiences rapid growth. Although still small enough to fit comfortably inside the uterus, your baby's body is becoming stronger and more coordinated every day.

By the end of the 4th month of pregnancy, your baby has reached several exciting developmental milestones.

Your baby now has:

• Stronger bones and joints

• Fully formed fingers and toes

• Unique fingerprints

• Developing eyebrows and eyelashes

• Facial muscles capable of making expressions

• Arms and legs that move freely

• A rapidly developing nervous system

• Working kidneys that begin producing urine

• A functioning digestive system

• External ears in their proper position

The placenta continues providing nutrients, oxygen, and immune support while producing hormones that help maintain a healthy pregnancy.

---

Baby Development During the 4th Month of Pregnancy (Weeks 13–16)

Baby development during the 4th month of pregnancy includes rapid growth of bones, muscles, facial features, and internal organs, while your baby becomes increasingly active inside the womb.

During pregnancy weeks 13 to 16, your baby grows almost twice as long as in the previous month. Body proportions become more balanced, movements become smoother, and many organs begin working together.

Let's explore these amazing developmental milestones.

---

1. Bones Become Stronger

One of the biggest milestones in baby development in the 4th month of pregnancy is the hardening of your baby's skeleton.

Soft cartilage gradually changes into bone through a process called ossification. Calcium and vitamin D play an important role during this stage, making a healthy 4th month pregnancy diet especially important.

Although the bones continue developing throughout pregnancy, they become noticeably stronger during the second trimester.

---

2. Baby Begins Making Coordinated Movements

Your baby becomes much more active during the 4th month pregnancy.

Inside the womb, your baby can:

• Stretch

• Kick

• Bend arms and legs

• Roll

• Open and close tiny hands

• Move the head

Although many of these movements are still too gentle to notice, some mothers—especially those who have been pregnant before—may begin feeling small fluttering sensations.

---

Facial Features Become More Defined

Your baby's face becomes increasingly recognizable during the 4th month of pregnancy.

Several facial features continue developing, including:

• Eyebrows

• Eyelashes

• Nose

• Lips

• Chin

• External ears

The facial muscles also develop, allowing your baby to yawn, frown, squint, and even make sucking movements.

---

3. Fingerprints Form

One fascinating milestone during baby development in the 4th month of pregnancy is the formation of fingerprints.

Tiny ridges develop on your baby's fingers and toes, creating a unique fingerprint pattern that remains unchanged throughout life.

---

4. Hair Begins to Grow

Fine hair begins appearing on your baby's scalp during the 4th month of pregnancy.

Lanugo, a soft layer of fine hair, also starts covering your baby's body. This delicate hair helps protect the skin and usually disappears before or shortly after birth.

---

5. The Nervous System Continues Developing

Your baby's brain continues growing rapidly throughout the 4th month pregnancy.

Millions of nerve cells form new connections that help coordinate movement, reflexes, and future learning.

As the nervous system matures, your baby's movements become smoother and more purposeful.

---

6. The Heart Works Harder

Your baby's heart is now fully developed structurally and continues pumping blood efficiently throughout the body.

At this stage, the heart beats approximately 120 to 160 times per minute, which is much faster than an adult's heartbeat.

During prenatal visits, your healthcare provider may monitor your baby's heartbeat using a Doppler device.

---

7. The Placenta Fully Supports Your Baby

By the 4th month of pregnancy, the placenta has become your baby's lifeline.

It performs several essential functions by:

• Delivering oxygen

• Providing nutrients

• Removing waste products

• Producing pregnancy hormones

• Offering immune protection

A healthy placenta plays a vital role throughout the remainder of pregnancy.

Your baby grows remarkably during pregnancy weeks 13 to 16. At the beginning of the month, your baby is about the size of a peach, and by week 16, your little one is roughly the size of an avocado.

Although still tiny, your baby's body has become much more proportionate. The head no longer appears overwhelmingly large, limbs are stronger, and coordinated movements become increasingly common.

One exciting milestone during baby development in the 4th month of pregnancy is that your baby can now make facial expressions, suck their thumb, yawn, stretch, and kick—even if you cannot feel every movement just yet.
