Officially, the third trimester indicates the period of pregnancy from the weeks between 28 to 40. This is the trimester when all of your fetal’s organs and systems are getting prepared for the real world. Your fetal will grow and gain weight throughout your entire pregnancy, but she or he will noticeably increase in size only during the third trimester. Here you will find all the information you need to know about your fetal weight gain in the third trimester.
The third trimester of pregnancy comes with a rapid development of your unborn baby. In fact, the beginning of the seventh month marks the third trimester. Your baby’s movements are going to become stronger; as your baby grows, he or she will have less room for it to move freely. Therefore, kicks and obvious changes in its position are going to become very clear and you’ll easily notice them.
Your fetus will really grow over the next few weeks to reach about 15-17 inches long and weighing around 4-5 lbs by the 32nd week of pregnancy. At this time, your baby’s lungs are yet to be fully mature, the bones are fully developed but are still soft.
Weeks 33 to 36
By this time, your fetus will descend into the head down position to get ready for birth. Your fetus is about starting to gain weight more rapidly. The lanugo hair (the hair that covers the body of some newborns which is very thin, soft, usually found in the body of a fetal or new-born human) will disappear from the skin and will become less red and wrinkled. The fetus is now about 16-19 inches and weighs about 5 to 6 lbs.
Weeks 37 to 40
The weeks 37 to 40 are the period when your fetus is considered full term and is ready to make his or her appearance at any time. As your baby becomes bigger, you may notice some changes in the fetal movement. Pay attention to the fetal movement and if at any time you noticed a decrease in the fetal movement, make sure to talk with your doctor right away.
In addition, the fingernails have grown long and will need to be cut soon after birth. Small breast buds are noticeably present in both baby boys and girls. At this time, you will be supplying your fetus with antibodies in order to help protect against disease. Moreover, all of the organs are developed, with the lungs maturing up until the day of delivery. Your fetus will be around 19-21 inches long and weighs about 6 to 10 lbs.
In a nutshell, you have to keep all of the scheduled prenatal visits to make sure that your baby is growing and developing properly. If your doctor suspects that your baby isn’t developing properly, he or she may order some special tests such as ultrasounds. In addition, your doctor will also monitor your weight as well as the baby’s weight. Although rapid weight gain is very common during the final months of pregnancy, excessive weight gain can be an alert of some potential problems such as gestational diabetes.
