Your baby now measures 6.3 inches (16 cm) from head to foot and weighs about 3.2 ounces (90 gm) at the start of the week—and about 4.2 ounces (120 gm) at the end of the week.
Although the baby’s head is still big in relation to the body, they are more in proportion. Your baby’s eyes are closed, but they’ve grown and both eyelashes and eyebrows have grown. More and more hair is growing on the head, and there are tiny nails on all fingers and toes.
Your baby is starting to store subcutaneous fat, which helps your baby to stay warm and provides energy.
Your baby can now hear and react to sounds from outside.
Your uterus is growing rapidly. The upper part is approximately halfway between your pubic bone and your navel.
Some women feel unusually warm, start to sweat more or experience shortness of breath due to an increase in blood volume. Many also experience nasal congestion as the mucous membranes swell, believed to be caused by high pregnancy hormone levels.
You may notice more vaginal discharge. Provided the discharge is odorless, you have nothing to worry about. However, if you notice an unpleasant odor, check in with your health care provider.
The mucous membranes in your nose and vagina may be delicate and bleed easily. If you are having problems with sensitive mucous membranes, use a lubricant when you have sex.
Your partner’s belly bump may be even more prominent—which is wonderful for you both. If you’re scheduled to have an ultrasound, you’ll be able to see the sex of your baby. Would you like to know whether you’re having a boy or girl, or would you rather wait until he or she is born?
