What's happening with baby
This week, your baby is roughly the size of a coconut, continuing their amazing growth and development. Their lungs are becoming more mature, and they're actively practicing breathing movements, inhaling and exhaling amniotic fluid. This is crucial preparation for taking those first breaths outside the womb. Your baby's brain is also rapidly developing, forming complex connections that will support their learning and sensory experiences. They're accumulating more fat layers, which will help regulate their body temperature after birth, and their kidneys are now fully developed and functioning. You might notice their movements feel a bit different now – perhaps more rolls and stretches than distinct kicks, as space inside your uterus becomes a little more snug.
What you might be feeling
Around 31 weeks, many pregnant people start to experience more frequent Braxton Hicks contractions. These are often described as a tightening sensation across your abdomen that comes and goes, usually not painful, and typically irregular. They're your body's way of practicing for labor, and they're a completely normal part of the third trimester. You might also find that fatigue is returning, as your body works hard to support your growing baby. Pelvic pressure or mild discomfort can become more noticeable, especially as your baby settles lower. Emotionally, you might be feeling a mix of excitement, anticipation, and perhaps some gentle anxiety about the upcoming birth and parenthood. Some people also experience a surge of "nesting" energy, feeling a desire to organize and prepare the home.
