Second Trimester Pregnancy Care
The second trimester is often called the “golden period” of pregnancy because many women experience increased energy levels and fewer early pregnancy discomforts. Spanning Week 13 to Week 27, this stage is marked by rapid baby growth, noticeable body changes, and exciting milestones such as feeling your baby’s first movements.
Following proper second trimester pregnancy care is essential to support your baby’s healthy development while maintaining your own physical and emotional well-being. During this period, eating a balanced diet, staying active, attending regular prenatal check-ups, and monitoring your baby’s growth all contribute to a healthy pregnancy.
This guide covers everything you need to know about second trimester symptoms, baby development, nutrition, medical tests, and expert pregnancy care tips.
