When a woman becomes pregnant, the baby will start developing from a fertilized egg to around 8lb at the time of birth. The process of fetal development passes through predictable stages with little variation from one individual to another. During the pregnancy, the doctor will monitor the growth of the baby to ensure that the baby is growing smoothly.Under the womb when the baby is not grown fully then it is called by the name fetus and if the fetus is not achieving all the expected growth then there can be some problem or complication in your pregnancy.
So to avoid these problems one should be aware of the signs of a healthy fetus.Till the 10th week of the pregnancy the baby is an embryo and becomes a fetus after the completion of the 10th week of the pregnancy. With the rapid growth of the baby the chances of external threats increases which creates a need for fetal behavior test and it should be checked with the help of routine tests and examinations so as to evaluate the health of the baby.
Signs of a Healthy Fetus
After completion of five months of your pregnancy, the baby will start moving in the uterus. The first movement by the baby is known as quickening. When six months of pregnancy begins, the baby starts responding to external sounds with jerky movements and sometimes the mother feels like the baby is taking hiccups.
At the beginning of the seventh month, the baby responds to stimuli like light or noise and pain. The baby starts changing its position in the eighth month and kicks a lot. The movement decreases when the ninth month starts as the baby has grown fully in the uterus and there is no space left for the movement. So you should always keep a check on these things and report all types of changes to your doctor timely.
Growth and Development
Some doctors recommend some routine tests to evaluate the growth and development of the baby. These tests include ultrasound which shows a 10 inches fetus of 5 month which increases 2 inches every month and by the seventh month it should be 14 inches and in the ninth month it becomes 18 to 20 inches long.
Some other tests that helps to trace the growth of the baby are kick count, nonstress test, biophysical profile and non stress test.
The heartbeat of the baby is traced by using electronic fetal monitoring. Some expert doctors trace this by touching your stomach as they count the beats on their own. The heartbeat of the baby needs to be monitored in the ninth month at the time of the labor also so as to ensure that the baby maintain a right heart rate that ranges between 110 to 160 beats in a minute.
Change in position at the time of Pre-labor
Although the movement of the baby ends in the ninth month but the baby for sure changes the position to get ready for coming to this world. By changing the position in the uterus, the baby drops into the pelvis and the head starts pointing towards the canal made for giving birth.
