What Is the Second Trimester of Pregnancy?
The second trimester of pregnancy begins at week 13 and ends at week 28. During this period, the placenta is fully functional, your baby grows rapidly, and pregnancy-related discomforts often decrease.
Why second trimester care matters:
- Rapid growth of baby’s organs and bones
- Early detection of fetal abnormalities
- Prevention of anemia, gestational diabetes, and hypertension
Body Changes in the Mother (Weeks 13–28)
During pregnancy weeks 13–28, several physical changes occur:
- Visible baby bump and weight gain
- Reduced nausea and vomiting
- Skin changes like pigmentation or stretch marks
- Mild back pain or leg cramps
- Increased vaginal discharge (usually normal)
These changes are expected, but regular antenatal visits ensure everything is progressing normally.
Baby Development in the Second Trimester
The second trimester is a period of remarkable fetal development:
- Weeks 13–16: Facial features form, baby can make expressions
- Weeks 17–20: You may feel the first baby movements (quickening)
- Weeks 21–24: Hearing develops; baby responds to sounds
- Weeks 25–28: Brain development accelerates; lungs begin maturing
By the end of week 28, your baby has a strong heartbeat, active movements, and a better sleep–wake cycle.
Antenatal Check-ups & Tests in Second Trimester
Regular antenatal care in the second trimester is essential for early diagnosis and prevention of complications.
Important Check-ups
- Blood pressure and weight monitoring
- Urine tests (infection, sugar, protein)
- Hemoglobin and blood sugar testing
Essential Scans
- Anomaly scan (18–22 weeks): Checks baby’s organs and growth
- Growth scans if advised by your doctor

Second Trimester Pregnancy Diet
A balanced second trimester pregnancy diet supports fetal growth and maternal health.
Foods to Include
- Protein: eggs, pulses, dairy, lean meat
- Iron-rich foods: spinach, dates, jaggery
- Calcium: milk, curd, paneer
- Omega-3: walnuts, flaxseeds
Foods to Avoid

According to ACOG Pregnancy Nutrition Guidelines, proper nutrition reduces the risk of anemia and low birth weight.
Exercise & Lifestyle Care
Safe exercise during the second trimester improves circulation and reduces stress.
- Walking for 20–30 minutes daily
- Prenatal yoga and stretching

Emotional & Mental Well-being
Hormonal changes can still affect mood. During weeks 13–28 of pregnancy:
- Practice relaxation techniques
- Communicate openly with family
- Attend antenatal classes
Mental well-being is as important as physical health for a healthy pregnancy.
Warning Signs During Second Trimester
Seek medical attention immediately if you experience:
- Vaginal bleeding or fluid leakage
- Severe abdominal pain or cramps

- Reduced baby movements
Early intervention can prevent serious pregnancy complications.
