5th month of Pregnancy (18-22 weeks)

By the fifth month of pregnancy (18 to 22 weeks), many expectant mothers start to feel more energetic as early pregnancy symptoms like nausea often finish. This is a time of significant fetal growth; the baby is developing features like hair, eyelashes, and the ability to hear sounds.
Physical changes in the mother become more noticeable, including a growing belly and potential discomforts like back pain or round ligament pain. Many women also report feeling more connected to their baby as they may begin to feel movements, known as flutters or kicks. Regular prenatal check-ups become increasingly important to monitor both maternal and fetal health during this exciting phase.

1. Common Pregnancy symptoms at 5th months pregnant
During the fifth month of pregnancy, common symptoms may include:
- Increased Energy: Many women experience a boost in energy as early pregnancy fatigue decreases.
- Visible Baby Bump: The belly becomes more pronounced as the uterus expands.
- Fetal Movement: Mothers often begin to feel the baby’s movements, which can feel like flutters or gentle kicks.
- Digestive Changes: Some may experience heartburn or indigestion as the growing uterus puts pressure on the stomach.
- Breast Changes: Breasts may feel fuller or tender, and some women notice darkening of the areolas.
- Skin Changes: The “pregnancy glow” may develop, but some might also experience darkening of the skin or the appearance of stretch marks.
- Back Pain: As weight increases, back discomfort can become more pronounced.
- Frequent Urination: The growing uterus may press on the bladder, leading to more frequent trips to the bathroom.
- Nasal Congestion: Some women experience nasal stuffiness or bleeding due to hormonal changes.
- Swelling: Mild swelling of the feet and ankles can begin as fluid retention increases.
- Leg Cramps: Some women may experience leg cramps, especially at night.
- Varicose Veins: Increased blood volume and pressure can lead to the development of varicose veins, particularly in the legs.
- Difficulty Sleeping: As the belly grows, finding a comfortable sleeping position may become challenging.
These symptoms can vary widely among individuals, and while many may experience them, others might not. Always consult a healthcare provider for advice.
2. Fetal Development

During the fifth month of pregnancy, fetal development progresses significantly. Here are key milestones for the fetus:
- Development of Features: The baby’s facial features become more distinct, with the formation of eyebrows, eyelashes, and hair on the scalp.
- Movement: The fetus becomes more active, and mothers may start feeling more pronounced movements, which can be described as kicks or rolls.
- Hearing: The baby’s ears are fully developed, allowing them to hear sounds from outside the womb, including voices and music.
- Skeletal Development: The bones continue to harden, and the baby begins to move more, practicing movements like stretching and yawning.
- Skin Changes: The skin is still thin and translucent, but it starts to develop a protective coating called vernix caseosa, which helps to protect the skin from amniotic fluid.
- Fat Accumulation: Subcutaneous fat begins to form, which will help with temperature regulation after birth.
- Internal Organ Development: Major organs, including the lungs and kidneys, are developing further, preparing for their functions outside the womb.
- Sexual Differentiation: If not already determined, the sex of the baby can often be identified via ultrasound during this month.
- Reflexes: The fetus starts developing reflexes, such as grasping and sucking, as they prepare for life outside the womb.
Overall, the fifth month is a critical period of growth and development.
3. Baby Bump
At five months pregnant, the baby bump becomes significantly more prominent, often taking on a rounded and firm shape as the uterus expands above the pelvic bone. This growth typically leads to noticeable changes in the mother’s body, prompting many women to transition to maternity clothing for comfort and support. The skin over the belly may start to stretch, with the possibility of developing stretch marks and the appearance of the linea nigra, a dark line running from the navel to the pubic area. This visible baby bump not only marks a key milestone in the pregnancy journey but also deepens the emotional connection between the mother and her growing child.
4. Size and Weight of Baby
At five months pregnant, the baby is approximately 10 to 12 inches long, about the size of a banana or a large carrot. The weight generally ranges from 1 to 1.5 pounds. During this month, significant growth occurs as the fetus continues to develop, gaining both length and weight. This increase in size is crucial for the baby’s overall development, as it prepares for the more rapid growth that will occur in the later months of pregnancy.
5. Getting an ultrasound at 5th months pregnant
Getting an ultrasound at five months pregnant, usually around weeks 18 to 22, is an exciting milestone for expectant parents. This mid-pregnancy ultrasound, often called the anatomy scan, serves several important purposes:
- Fetal Development: The ultrasound provides a detailed view of the baby’s growth and development, allowing healthcare providers to assess the size, position, and anatomy of the fetus.
- Checking Organs: Technicians examine major organs, including the heart, brain, kidneys, and spine, to ensure they are developing properly.
- Gender Determination: If the parents wish to know, this scan often reveals the baby’s sex, provided the baby is in a position that allows for a clear view.
- Amniotic Fluid: The ultrasound checks the amount of amniotic fluid surrounding the baby, which is crucial for fetal well-being.
- Placenta Position: The position of the placenta is assessed to ensure it is properly situated and not covering the cervix.
This ultrasound typically lasts about 30 to 45 minutes and is a key part of prenatal care, helping to ensure both maternal and fetal health.
6. Fetal Movement at 5th months pregnant
At five months pregnant, typically around weeks 18 to 22, fetal movement becomes more noticeable and can be one of the most exciting aspects of pregnancy. Here are some key points about fetal movement during this stage:
- Feeling Movements: Many mothers begin to feel distinct movements, often described as flutters, bubbles, or gentle kicks. These sensations can vary widely among women, with some feeling movement earlier than others.
- Increased Activity: As the month progresses, movements may become more pronounced and frequent, reflecting the baby’s growth and development. Some mothers may feel the baby rolling or stretching.
- Timing of Movements: Fetal movement patterns can vary, with some babies being more active during certain times of the day or after the mother eats, likely responding to changes in blood sugar levels.
- Sign of Health: Regular movement is generally a sign of a healthy fetus. If there are noticeable decreases in movement later in the pregnancy, it’s important to consult a healthcare provider.
Overall, fetal movement during the fifth month is an exciting development, marking an important phase in the pregnancy journey.
7. Exercise and Diet at 5th months pregnant
During the fifth month of pregnancy, maintaining a balanced exercise routine and a nutritious diet is essential for both the mother’s health and the baby’s development. Here are some key considerations:
Exercise:
- Types of Exercise: Low-impact activities like walking, swimming, and prenatal yoga are generally safe and beneficial. These exercises can help improve circulation, reduce discomfort, and boost energy levels.
- Flexibility and Balance: Stretching and balance exercises can help alleviate tension and prepare the body for labor.
- Consultation: Always consult with a healthcare provider before starting or continuing an exercise.
- Listen to Your Body: Pay attention to how you feel during and after exercise. If you experience pain, dizziness, or shortness of breath, it’s essential to stop and consult a healthcare provider.
Diet:

- Balanced Nutrition: A diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats is vital.
- Hydration: Staying well-hydrated is crucial, as it helps with digestion and circulation. Aim for at least 8-10 cups of water daily.
- Key Nutrients:
- Protein: Important for fetal growth; sources include lean meats, dairy, legumes, and nuts.
- Calcium: Supports bone development; found in dairy products, leafy greens, and fortified foods.
- Iron: Necessary for increased blood volume; sources include red meat, beans, and fortified cereals.
- Folic Acid: Essential for neural development; found in leafy greens, fortified grains, and citrus fruits.
- Avoid Certain Foods: Limit or avoid high-mercury fish, unpasteurized dairy, and raw or undercooked meats to reduce the risk of foodborne illnesses.
By focusing on appropriate exercise and a well-rounded diet, mothers can promote a healthy pregnancy and support their baby’s growth and development. Always consult a healthcare provider for personalized recommendations.
