Tooth buds are developing.
The bones continue to form and are getting harder with each passing day.
Your uterus is now rising above your hipbones, and you may feel it about 3 inches (around 8 cm) below your navel.
Your enlarged heart is pumping about 20% more blood than before in order to supply blood your baby with oxygen, and this figure may increase to as much as 50% later on.
