You are now 10 weeks pregnant (56 days after conception), which is the beginning of week 11. Your baby measures about 3.5 cm (or 1.4 inches) and weighs about 5 grams (or 0.18 ounces). By the end of this week all your baby's major organs will be in place. Over the following months before birth, they will continue to grow and mature.
Your baby's legs are now longer than their arms and the large muscles in their arms and legs have developed, forming thick bands of padding between their skin and underlying bones. Your baby's brain and nervous system are maturing, their muscles and nerves now working together to facilitate your baby's first movements. Initially the movements are only small, jerky and uncoordinated and the baby is far too small for the mother to feel any movements within. Your baby now has primitive reflexes and can respond to touch if stroked on the palm of their hands or the soles of their feet.
Your baby can now open their jaw and stretch. Their body is straighter and small ribs can be seen through their chest. Their digestive system is developing rapidly and they are about to have a growth spurt!
