Do you know when you are pregnant? At what time will you be able to hear this wonderful sound?
Hearing your baby's heartbeat is an exciting milestone for first-time parents. Your baby's heart rate can be detected early with transducer ultrasound from 5.5 to 6 weeks after pregnancy. That is when the fetal polarity, the first sign that the embryo is developing, may have appeared.
However, it is not until the fetus is 6.5 to 7 weeks that the fetal heart is clear. That's when your doctor scheduled an ultrasound for the first time to check for signs of a healthy pregnancy. So when will you be pregnant, follow along!
What will pregnant mothers be checked at the first antenatal visit?
After a positive pregnancy test, your doctor may recommend that you schedule a pregnancy ultrasound exam as early as 7 to 8 weeks of pregnancy.
However, your doctor may recommend an ultrasound scan as early as 6 weeks if you're pregnant:
Have a previous medical condition
Have had a miscarriage
Pregnancy is difficult
During your first ultrasound appointment, your doctor or sonographer will check for the following:
Check the status of pregnancy, exclude ectopic pregnancy
Confirm your baby's heart rate
Measure the length from head to butt of the fetus and determine gestational age
Abnormal pregnancy assessment (if any)
When the fetus has a fetal heart?
How many months pregnant have fetus heart? The fetal heart rate ranges from 90-110 beats per minute (bpm) at 6 to 7 weeks. By week 9, your baby's heart rate will reach 140-170 bpm.
You may not be able to hear your baby's heartbeat on the first scan. Usually, this ultrasound is too early to see the fetal heartbeat does not mean the fetus has problems.
Your doctor may advise you to schedule another scan 1 to 2 weeks later.
Reasons for your baby's heart rate unknown include:
Have the uterus tilted
Mom has a big belly
Pregnancy is not enough time
If the heart rate is not detected , the doctor will check your baby's measurements. If the fetus does not have a fetal heart and is greater than 5 mm in length, the doctor will need further monitoring.
Pregnant several weeks to have a pregnant heart? After 6 weeks, not having a pregnancy bag is a worry. The doctor may order a blood test to confirm the pregnancy, or ask the pregnant mother to do some other ultrasound.
A 1999 study of 325 UK women with a history of miscarriage reported that if the heart rate is heard after 6 weeks, pregnant mothers have a 78% chance of having a smooth pregnancy. At 8 weeks, there's a 98% chance and goes up to 99.4% after 10 weeks.
What techniques are used to hear the baby's heartbeat
During the first visit, the doctor or sonographer will use a transducer ultrasound, or 2D or 3D abdominal ultrasound.
Transvaginal ultrasound is used during early pregnancy to obtain a clear picture of the embryo. 3D ultrasound allows the doctor to see more clearly the width, height and depth of the fetus and the organs inside the abdomen.
Can you hear your baby's heart with your ear?
Detecting fetal heart by human ear is very difficult, if not impossible. But some mothers expect they can hear their baby's heartbeat through their tummy. This can happen in a quiet room during the second or third trimester.
Do not worry if the pregnant mother cannot hear her baby's heartbeat at home.
If you're concerned about your baby's heart rate, the safest option is to contact your doctor. They may schedule ultrasound tests to make sure your baby's heart rate is normal.

During pregnancy, your baby's heart will continue to grow. The fetal heart rate starts at 90 to 110 bpm during the first weeks. It will rise and reach a weekly high from 9 to 10, from 140 to 170 bpm.
Thereafter, normal fetal heart rate was weighed between 110 and 160 bpm during the second and third trimesters. Remember, your baby's heart rate may change during pregnancy and at every prenatal visit.
The doctor may worry if your baby's heart rate is too slow, too fast, or irregular. In rare cases babies may develop heart disease. That is why the doctor will monitor your baby's heart rate during every appointment.
If your doctor has any concerns about a fetal heart, they may schedule an ultrasound for further tests
Note for pregnant mother
The doctor will monitor the baby's heart rate during each prenatal visit. Pregnant mothers can hear the baby's heartbeat for the first time after 6 weeks.
If you are concerned about your child's heart rate and still have questions about what month it is, talk to your doctor!
