Symptoms and Baby Growth at 5 Months Pregnant

The fifth month of pregnancy (weeks 17–20) marks an exciting milestone — your baby is growing rapidly and you may begin to feel those first flutters of movement.

Fetal Development at 5 Months

By week 20, your baby is approximately 25 cm long and weighs around 300 grams. Key developments include:

• Eyebrows, eyelashes, and hair are forming
• Fingernails and toenails are growing
• The baby can hear sounds and may respond to your voice
• Limb movements become more coordinated
• A white, waxy substance called vernix caseosa coats the skin

Common Symptoms at 5 Months

What you may experience:

• Quickening — the first felt baby movements, often described as flutters or bubbles
• Round ligament pain — sharp pain on one or both sides of the lower abdomen
• Backache — as your centre of gravity shifts
• Nasal congestion — due to increased blood volume and hormonal changes
• Heartburn and indigestion — as the uterus grows and presses on the stomach
• Swollen ankles and feet — normal unless accompanied by headache or visual changes
• Increased appetite — your baby needs more nutrition now

Nutrition Tips for the Fifth Month

Focus on:

• Calcium-rich foods: milk, yogurt, cheese, ragi
• Iron sources: spinach, lentils, lean meat, dates
• Protein: eggs, legumes, fish (low mercury)
• Healthy snacks: fruits, nuts, and yogurt
• Stay well hydrated — aim for 8–10 glasses of water daily

Warning Signs to Watch

Seek medical attention immediately if you experience:

• Heavy bleeding
• Severe abdominal pain
• Fluid leaking from the vagina
• No fetal movement after week 20
• Fever above 38°C
• Swelling in the face or hands

The mid-pregnancy anomaly scan (typically done around week 20) is an important milestone to confirm the baby's anatomy. Iswarya Hospital's OBG team provides comprehensive antenatal care throughout your pregnancy journey.
