At the 37th week your baby has a height over 48 cm and a weight of 2900 g. His/her brain and skull continue to grow. During these weeks, your doctor will perform a pelvic examination and determine whether your skeletal structure is appropriate for delivery, or not.

At the 38th week your baby is considered to reach his/her term and your precious visitor may come at any time during the following two weeks. His/her height exceeds 50 cm and his/her weight exceeds 3000 g.  The fine hairs covering your skin and the waxy substance called vernix are falling off.

In the last month your baby takes the position of delivery within your uterus. He/she has now a weight of 50 cm and a weight of 3-3.5 kg.

Hairs on the skin may start to fall off. The creamy layer on his/her skin decreases. Now, all belongings of your baby have to be ready, it is normal for him/her to come a short time before or after his/her normal date of delivery.  Keep your bag ready to leave for the hospital, place all materials and clothes that will be necessary for you and for your baby in it. Keep a nightgown, socks to keep your feet warm, slippers and have anything that you think you will need with you ready. Do not forget to prepare your baby’s clothes. Prepare his/her room, as well. Do not forget that regular contractions that point to delivery may start now.

Only 5% of the babies are born on the exact estimated date, the remaining are born within the period of 15 days before and after the normal delivery date. You have put on a lot of weight throughout your pregnancy. You may have put on 10-15 kg. Your low back pain may increase, you may have difficulty in walking.
