Many pregnant women hear that progesterone is low in the early stages of pregnancy, especially during the first prenatal check-up, where doctors will check for progesterone. If progesterone is low, the doctor will recommend that you supplement progesterone. So, if heart dilation is detected at 12 weeks of pregnancy, is it normal? Let's learn about it together!
Fetal heart rate often reflects changes and developmental levels of the heart. At 12 weeks, the fetal heart rate is normal, and the regularity of normal fetal heart rate is strong. The fetal heart rate is between 120-160 beats per minute. If the fetal heart rate frequently exceeds the normal range, it is likely due to delayed heart development or dysfunction. So we need to take measures to deal with it.
Special instruments are needed to listen to fetal heart rate. At around 12 weeks of pregnancy, fetal heart can be heard using a stethoscope in a very quiet situation, but if an obstetric stethoscope is used, it can only be heard at 18 weeks of pregnancy.
In most cases, abnormal fetal heart rate means that the fetus is deprived of oxygen in the uterus. The greater the degree of abnormal fetal heart rate, the more severe the lack of oxygen in the fetus. So, is it true that all abnormal fetal heart rates are caused by a lack of oxygen?
The condition of pregnant women can also affect changes in fetal heart rate. When pregnant women have a fever, the fetal heart rate often exceeds 160 beats per minute, leading to hyperthyroidism in pregnant women. The pregnant woman's own heart rate is very fast, and the fetal heart rate often exceeds 160 beats per minute. If there is indeed fetal hypoxia at this time, early delivery is necessary.
