What's Going On in Your Belly at 35 Weeks Pregnant?
The fetus is around 18 inches long (crown to heel) and weighs approx. 5 lbs.
During late pregnancy, three particular examinations are sometimes performed to check on how the baby is doing and whether the organs are working correctly:
#1 Calculation of the amount of amniotic fluid
With the aid of an ultrasound scan, it is possible to determine how much amniotic fluid is present in different areas around the baby. These values can be used to calculate the total quantity. If it is too low, this can be a sign that the baby's metabolism or kidneys are not working correctly.
#2 Doppler ultrasound
This examination, which is also called a "color flow doppler", is a special form of ultrasound that makes the function of various blood vessels visible. The flow of blood to and from the uterus, the placenta, and the baby's head is monitored. Excessively large blood vessels and certain gaps in the recorded blood pressure may indicate problems or a deficiency.
#3 CTG (cardiotocography) examination
The CTG records the sounds of the heart and contractions. It is also referred to as a "fetal monitor". This means it can be used to monitor both the baby's heartbeat as well as the uterine muscles. This type of examination usually takes place on or around the due date, although it may also be performed if there is a suspicion of premature contractions or for safety reasons during an external cephalic version. During labor, the CTG is used to keep an eye on how the baby is handling the contractions. The CTG "draws" 2 lines: one describes the heartbeat and the other indicates the activity level of the uterus.
Inside the uterus, the baby's heart beats at a rate of approximately 120-160 beats per minute. Movements of the fetus and external stimulation usually result in the baby's heartbeat rising. When a CTG is evaluated, attention is paid to such increases and decreases. Interpreting the findings is not simple and frequently takes place with the aid of computer programs – and ideally in combination with experienced midwives.
