17 Weeks Pregnant – Pregnant Symptoms Week By Week

At week 17 into your pregnancy, the body is frantically making adjustments to create space for the explosive growth of the fetus expected in the subsequent months. The baby’s facial expression continues developing in this week with the eyebrows and eyelashes starting to appear. It will be a week of intensive growth.

Your Baby at 17 Weeks Pregnant

By the 17th week, the baby has grown bigger and weighs 6 ounces and measures 5 inches long from the rump to the crown. He/she has started developing a layer of fat under the skin. More layers will be added in the coming weeks. The additional fat helps to provide the baby with warmth in the womb and even after birth.

The baby’s skin starts producing a white and greasy film referred to as vernix. This helps to protect the skin, internal organs, and aid in temperature regulation.

The baby’s toes and fingers continue developing so that they are completely differentiated. The toes continue developing for the remaining part of pregnancy and might even need trimming after birth. Another important thing about the baby at 17 weeks pregnant is the continued sucking of the thumb. However, you need to appreciate that the sucking is simply out of reflex. This sucking of the thumb serves several purposes:

  • The baby practices how to suck so that sucking the mom’s breasts will be natural after birth.
  • The sucking helps the baby to take some amniotic fluid through the mouth to practice the digestive system.
  • Some of the amniotic fluid is sucked through the nose and helps with the development of the respiratory system.

By the close of week 17, the baby is busy working on the circulatory system. The blood vessels development that started developing a few weeks ago will intensify and some blood flow might be noticed towards the end of the week. However, clear blood flow will be evident in the coming weeks. The lymphatic flow system is also developing rapidly but its activity will not be noticeable until the subsequent weeks.

Now, the baby’s auditory senses are well developed and can easily pick noises in the neighborhood. Therefore, he/she keeps moving when sounds are made in the neighborhood. From this week going forward, it is advisable to stay away from loud noises that can frighten the baby. You should also avoid noisy confrontations.

Your Body at 17 Weeks Pregnant

The growing baby bump has now become big enough and people around you have no doubt that you are pregnant. The additional weight, multiple needs for you & baby, and hormonal changes can result in anxiety. As everything about the pregnancy becomes clear, you might start wondering about the changes that the baby will bring once it is born.

By now, you might have noted major changes in your breasts. Unlike in the previous weeks when they were simply enlarging and becoming tender, you will start noticing darker veins appearing on the breasts to help ease the flow of nutrients to make milk for the baby. The rate of breasts growth will also be faster. Therefore, it is advisable to go for a professional bra that properly supports the breasts without restraining their growth. If you had not started feeling the baby in week 16, you are likely to start getting the soft butterfly-like movements this week.

17 Weeks Pregnant is How Many Months?

At week 17, you are in the fourth month. This means you are about three weeks to mid-pregnancy.

For example, bones, ligaments, muscles, and head are already formed.
