After pregnancy, many women pay special attention to the growth of their babies. At a certain period or time, they can see the fetal heart rate through examination. However, they are not very familiar with this knowledge, and many pregnant women want to see their babies' fetal heart rate as soon as possible. So how much estradiol causes fetal heart rate?
During pregnancy, estradiol levels are elevated and continue to rise, but there is no specific value to say how high estradiol levels will cause fetal heart rate. Generally speaking, after ultrasound examination, it is considered an intrauterine pregnancy. At 35 days of amenorrhea, a round or oval gestational sac can be seen in the uterine cavity, and at six weeks of pregnancy, the embryo and primitive heartbeat can be seen.
Precautions during pregnancy include the following:
1. Nutrition during pregnancy: not only ensure adequate nutrition, but also avoid excessive nutrition. It is ideal to maintain the weight gain during pregnancy at 12.5kg, to avoid the occurrence of full-term low weight infants or macrosomia, to eat a small number of meals, to avoid excessive fluctuations in blood sugar, and to avoid diabetes during pregnancy;
2. Pregnancy examination: Pay attention to prenatal examinations, which are beneficial for better understanding the baby's condition, such as NT examination, 4D ultrasound, glucose tolerance test, which are very important for maintaining maternal and infant health;
3. Pregnancy mood: During pregnancy, excessive work and life pressure can easily cause anxiety, which is not conducive to the health of mother and baby. Attention should be paid to relieving stress and maintaining a cheerful mood.
