Week 18 starts on day 126 and goes up to day 133.
It is your 19e pregnancy week.

Length of your baby: 20 centimeter / 7.9 inches
Weight of your baby: 200 gram / 7 ozs

The tiny nerve cells of your baby continue to develop and through little blood vessels fluid will be transported to the brain and the spinal chord. This fluid must be able to flow back and forward or the baby can develop water in the brain. Even if this does happen it is now possible to correct this while the baby is still in the womb. The brain of the baby grows very quickly now as much as 90 gram per month!

If this is your first pregnancy your tummy may still not be visible with your clothes on however if this is your second or subsequent child then you may be developing quite a paunch by now. From now on sleeping on your stomach will become increasingly difficult and you should try to start getting used to sleeping on your side, preferably your left as this allows the blood to flow more freely to your heart which is best for you and your baby. Your heart will now pump 40 to 50% faster than normal which is fine for a healthy heart and light exercise is till possible. Make sure however that you continue to eat healthy and get enough rest.


Most pregnant women will at some point during their pregnancy experience back pains and you may already have felt a twinge. Your uterus is now similar in size to a melon and as the focus and weight of your body moves forward this will put pressure on your lower back which can result in discomfort and pain. Be careful with bending and lifting and ensure you bend at the knee and not the spine. Try to stand as straight as possible and don't lean back too much to compensate for the weight at the front of your body.

@JRamos - “I`m 18 weeks but whe...„
Totally normal. Your due date can change a lot as it`s only an estimation anyway. My sizing both pregnancies has changed my due date a number of times

Don`t panic
