Your baby's development

By the fifth week of pregnancy, your baby is now an embryo.

Their head is growing in size due to the rapid development of their brain and the neural tube closes around week four of their development. Meanwhile, the brain and other major organs continue to grow.

Your baby’s heart is already beating and pumping blood around their tiny body. Their arm and leg buds are starting to develop.

Your body

As your uterus adapts to your growing baby you may experience light cramping. Other symptoms are likely to be very subtle at this early stage, but may include tiredness, tender breasts, nausea and headaches.
