Week 37: Your Baby is Considered Early Term
You may lose your mucus plug this week, which can look like a blob of clear, pink, or blood-tinged mucus. This is a sign that your cervix is starting to prepare for labour, though it doesn't mean labour is imminent. You may feel restless and anxious as your due date approaches.

Baby Development
The baby is now considered 'early term'. The lungs are mature enough to function outside the womb for most babies. The baby is practising inhaling and exhaling amniotic fluid, grasping, and turning from side to side. Head circumference and abdominal circumference are about the same. The baby is gaining about 200 grams per week, mostly in fat.
Week 37 Highlight: Your baby is now considered early term - their lungs are mature and they could breathe on their own if born today!
