Your 3rd trimester typically starts at week 29 and lasts until week 40. At this time your baby can open his eyes and turn his head in-utero if he notices a continuous, bright light shining from outside. Baby’s eyes are sensitive to light. Your baby now weighs about 1150gm and is about 38.5cm long from head to heel.
