From the time you conceive till the birth of the child, your body undergoes different changes. One of the many processes going on is the development of the baby. This is quite a delicate process — the time sperm and egg meet, to the formation of the baby, till its development.
Pregnancy and Ultrasound Scans
Ultrasound scans are performed at different stages of pregnancy to check the health of the baby along with other essential information like growth of the baby, any abnormality, placental position etc. They also help in letting the doctor know if the pregnant woman is carrying a single child or more. Ultrasound scans are tests done with the help of sound waves that provide visual images of the baby along with the placenta, uterus and other organs.
Detection of Baby’s Heartbeat
As every woman is different from another, so is their pregnancy. So, the time of detecting the baby’s heartbeat also varies. But, in general, by the beginning of the sixth week, the heartbeat of the baby is visible by doing an ultrasound scan. At this stage, the heartbeat is just like a flicker on the chest of the baby. However, in some cases, you may not see the heartbeat by the sixth week. But there is nothing to worry about. The normal heart rate of a baby at the beginning is around 90 to 110 beats per 60 seconds.
When the embryonic heartbeat is detected on the sixth week, it indicates that your pregnancy is safe and there is a little chance of miscarriage. In pregnancies, where the embryonic heartbeat is not detected in this period, the mothers-to-be are required to do another scan after 3 to 5 days. As the pregnancy progresses i.e. on the 9th week, the average heartbeat of the foetus would be around 120 to 160 beats per 60 seconds.
