Most women have gained about 19 pounds by this point in pregnancy. The weight gain is made up of the baby, the placenta and the amniotic fluid as well as enlarged breasts, an increase in blood volume, water storage, fat and protein.
You feel your baby moving about regularly and this may cause you to feel bonded with him. You don't need to worry though if you do not already feel bonded with your baby. For some women, the baby still seems abstract when it is inside. You may bond rapidly or gradually after the birth.
Fatigue will probably continue and you may feel breathless after physical activity.
Colostrum may be leaking from your breasts. However, this does not occur for all women and in no way indicates that there will be a problem breastfeeding if colostrum is not present before birth.
You may have trouble sleeping for various reasons: it may be difficult to find a comfortable position, you may have to urinate frequently during the night, baby's activity can prevent you from sleeping and you may be feeling anxious.
Your back probably aches since the muscles and ligaments that support it have begun to relax and loosen in preparation for labor.
You may have also developed some varicose veins.
My Baby This Coming Week
Your baby now weighs about 3.5 lbs (1600g) and measures about 18 inches (40cm) in total and about 11.2 inches (28cm) from crown to rump.
Your baby's increasing size means that she has less room to move around in your uterus.
Your baby could already be moving into the head-down position.
Your baby's lungs are maturing and their lining, which prevents air sacs from collapsing, is growing. This lung development means that your baby would have a much greater chance of survival if he were born prematurely.
About 16 fluid ounces of blood are flowing through the wall of your uterus to the site of the placenta, though your blood never mixes with your baby's blood. It is separated by the placental barrier which is a very thin wall. Water, nutrients and waste are exchanged across this barrier at a rate of 0.3 fluid ounces per second.
Your baby swallows amniotic fluid and urinates.
Your baby's ears are sufficiently developed to hear and recognize your voice, the voices of other family members as well as familiar musical tunes.
