Babies move around a lot at this time, and they are not settled head down (the usual position for birth) for some time yet. Large meals may make you feel uncomfortable. This might carry on for the rest of your pregnancy. Aim to eat smaller meals more often! You may find your breathing is affected a little by your growing uterus - extra effort may leave you slightly breathless. This is because your uterus is pushing against your diaphragm, leaving less space for your lungs. Your baby's blood circulation is completely functional. The umbilical cord system continues to grow and thicken as blood travels with considerable force through the body to nurture the baby. The placenta is now almost equal in size to the baby.
