When Does the Second Trimester Start?
The second trimester begins at week 13 and lasts until week 28. This is when:
- Morning sickness (nausea in the second trimester) often subsides.
- Your baby’s organs mature rapidly.
- You’ll likely have your second-trimester ultrasound (anomaly scan at 18-20 weeks).
Pro Tip: Use a pregnancy tracker app to monitor milestones!
Second Trimester Pregnancy Symptoms
Common Symptoms
- Reduced nausea but lingering sickness:
- 30% of women still experience morning sickness in the second trimester due to hormonal shifts.
- Remedy: Eat small, frequent meals and try ginger tea.
- Visible baby bump: Your uterus expands, causing a rounded belly.
- Feeling baby movements (quickening): Most women feel kicks between weeks 18-22.
- Back pain & leg cramps: Due to weight gain and ligament stretching.
- Nasal congestion & bleeding gums: caused by increased blood flow.
Lesser-Known Symptoms
- Glowing skin (thanks to hormones!)
- Linea nigra (a dark line on the belly)
- Shortness of breath (your diaphragm gets crowded)
⚠ Warning Signs: Severe dizziness, bleeding, or reduced fetal movement require immediate medical attention.
Second Trimester Ultrasound & Tests
- Anatomy Scan (18-20 weeks):
- Checks baby’s brain, heart, spine, and gender (if you want to know!).
- Detects 90% of significant abnormalities.
- Gestational Diabetes Screening (24-28 weeks):
- A glucose test to monitor blood sugar levels.
- Blood Tests: For anemia and infections.
