The uterus is growing steadily and will soon make its way out of the pelvic cavity which will make your growing pregnancy more obvious.

Week 14: Your feelings of tiredness and lethargy are now disappearing and you are feeling more active. You might want to consider enrolling in a regular prenatal exercise class which will help to tone up your muscles for the labor and delivery process as well as keep you free from aches and pains. Most women will also develop a dark line which runs down the centre of your abdomen and is called the lineanigra. This is due to hormonal changes and will disappear after the birth of the baby. The baby now even has eyebrows and hair starts to sprout on the head. You can hear the baby's heartbeat through the Doppler in your doctor's office.
