The sound produced by fetal cardiovascular pulsation is called fetal heart rate. Pregnant mothers are very concerned about when their babies have fetal heart sounds and want to feel their baby's heartbeat. When does the baby's fetal heart rate occur?
Women with a normal menstrual cycle can see cardiovascular pulsation through ultrasound after seven to eight weeks, or about 40-50 days, from the first day of their last menstrual cycle. However, some women may have irregular and prolonged menstrual cycles, and may not be able to see fetal heart rate around 40-50 days of pregnancy. Don't worry too much, you can have a follow-up examination 1-2 weeks later. If there is fetal heart rate, it can be determined that it is a live fetus in the uterus. After about 12 weeks of pregnancy, fetal heart rate can be heard with the help of special instruments. From the 16th week of pregnancy, the fetal heart can be heard from the pregnant woman's abdomen through a fetal heart tube. If the pregnant woman's abdominal wall is thick, the fetal heart can often be heard from the abdomen at the 20th week of pregnancy.
Expectant mothers must pay attention to resting more, maintaining a calm mindset, and avoiding excessive emotionality during pregnancy to avoid affecting the development of the fetus. The fetal heart rate can to some extent reflect the health status of the fetus. Generally, the fetal heart rate is 120-160 beats per minute, which is much faster than the adult fetal heart rate. If the pregnant woman's emotions fluctuate too much, it can also have a certain impact on the fetal heart rate.
If the fetal heart rate develops normally, a hospital registration is required. The doctor will conduct corresponding examinations based on your gestational age, remember to take folic acid tablets orally, prevent fetal neural tube defects, prohibit sexual activity in the early stage, and be alert to miscarriage.
