Pregnancy Week 13 — First Week of the Second Trimester
Pregnancy Week 13 marks the beginning of the second trimester. Baby is peach-sized, movements increase, and energy often returns. Learn what to expect this week.
🌸 Intro — First Week of the Second Trimester
Welcome to **Week 13**! 🎉 You’re officially in the second trimester, often called the “honeymoon phase” of pregnancy. Many moms feel a boost in energy, reduced nausea, and more comfort in daily activities. Your baby is growing fast and starting to look even more like a tiny human. Week 13 marks a pivotal stage in development as major systems continue to mature.
👶 Baby’s Development — Tiny but Growing Fast
This week, your baby is about the size of a **peach** 🍑 (~7–8 cm), weighing around 23 grams. - **Head & Face:** Neck starts straightening, jaw and chin more defined, eyelids fused but moving, ears in near-final position. - **Limbs & Movements:** Arms and legs grow longer; tiny fingers and toes fully separated. Baby can make small movements like stretching, bending, and kicking (though you won’t feel them yet). - **Internal Organs:** - Kidneys produce urine, stomach produces digestive juices. - Liver continues making red blood cells. - Brain is developing rapidly, and nerves are connecting. - **Genitalia:** External organs continue forming — sex may be detectable via ultrasound soon. - **Movements:** Tiny reflexes appear; your baby can open fists and bend elbows.
