High fetal heart rate is boy or girl? Studies have shown that the link between fetal heart rate and sex is completely inaccurate. The following article will explain to mom why.
Heart rate is one of the first factors to help obstetricians be aware of fetal development. Pregnant mothers will be very surprised to learn that the baby's heart rate will change with each week of pregnancy.
The fetal heart begins to appear from day 16 of pregnancy. At this time, the shape of the fetal heart has not been formed, but the heart is active, beating and contracting.
After that, the fetal heart will develop and complete more quickly after week 4.
During the 5th week of pregnancy, the fetal heart rate has a rate of about 80 beats per minute. The embryo forms more cells and a small particle between the embryo develops into the fetal heart. At this time, however, the mother still cannot hear the baby's heartbeat.
By the 6th week, your baby's heart beats about 110 beats a minute.
From week 7, your baby's heart begins to divide into the left and right chambers. At this time, the baby's heart rate will increase to 150-170 beats per minute, 2 times faster than the mother's heart rate.
By week 12, the heart beat normally.
Week 16, the baby's heart can pump blood with an amount of about 24 liters / day.
Gestational heart rate is about 140 beats per minute, at 24 weeks (average mid-pregnancy heart rate is 120 to 160 beats per minute)
From the next weeks of pregnancy until the baby is born, the fetal heart continues to grow in size and volume. Normally, the fetal heart beats from 120 to 160 times / minute.
Guess the sex of the baby in the womb is always the most thrilling part for parents. Relying on the fetal heart to know the sex of the baby is one of the ways inherited in "pregnant women".
Prospective mothers believe that if the heart rate is above 140 beats per minute (bpm), the fetus is a girl, below 140 bpm, it is a boy.
But unfortunately, obstetricians said that there is no basis to say that the high fetal heart rate is a boy or a girl.
The reason is that fetal heart rate changes from week to week and tends to increase, fetal heart rate continues to increase until it peaks around 9 weeks, from 140–170 bpm for boys and girls. .
Currently, with the development of medicine, there are many studies investigating the relationship between heart rate and sex showing that, fetal heart rate in the first 3 months is not a reliable indicator to say. the sex of the fetus.
The American Journal of Obstetrics and Gynecology (2014) has demonstrated the difference between the heart rate of boys and girls during labor. The girl's heart rate will now be a little higher than that of a baby boy from the moment the mother feels colic until the time of giving birth, and not any other time.
Therefore, guessing the sex of the fetus through the mother's heartbeat should only see this as a reference form to determine the sex of the baby.
Usually fetal heart rate will get higher as the baby grows up in the first trimester. If you find that your fetal heart is beating abnormally fast, instead of thinking about the sex prediction, you need to understand the reason why. Such as:
The fetal heart is beating fast after the mother eats it full. This is due to the machine fetus so the mother does not need to worry too much.
The fetal heartbeat is fast due to lack of oxygen, usually occurring mid- or late-pregnancy. Mother needs to combine with gestational signs (children do not have machines or very few).
Pregnant mother is sick, has fever or unusual symptoms of health.
The fetal heart rate is abnormally fast at 200 beats / min and can cause dangerous complications for the fetus. At this time, the best pregnant mother should go to a doctor to check carefully the parameters through ultrasound and receive advice from a doctor.
