Is it normal to have no fetal heart rate at 52 days?

Is it normal to have no fetal heart rate at 52 days?

The so-called fetal heart rate specifically refers to the heartbeat of the fetus. The fetal heart rate is an important indicator of the condition of the fetus in the uterus. As for when the fetal heart rate begins, there is no standard answer. The earliest time you can hear the fetal heart rate is the 17th week of pregnancy, and the latest time is the 20th week of pregnancy. At 52 days of pregnancy, it is still in the early stages of pregnancy. It is completely normal not to hear the fetal heart rate at this time.

Is it normal to have no fetal heart rate at 52 days?

Generally, the embryo bud and fetal heart rate can be seen after seven weeks of pregnancy. If there is no embryo bud and fetal heart rate, it may be fetal demise. The situation may be fetal growth retardation, but for the sake of caution, it is recommended to recheck the color ultrasound one week later to further clarify it. If no embryo bud and fetal heart rate are found after the color ultrasound examination, termination of pregnancy is recommended.

If the menstrual cycle is normal, conception occurs during the ovulation period, and there is no embryo or fetal heartbeat on the 52nd day of pregnancy, there may be a possibility of fetal developmental retardation or arrest. It is recommended to observe for a week and review the B-ultrasound results. If there is still no embryonic heartbeat, the embryo may have arrested development.

You are 52 days pregnant. It may be that your menstrual cycle is irregular, ovulation is late, and the number of days for conception is small. It is recommended to have a color ultrasound check again after one week.

Fetal heart rate and fetal bud are two very important indicators in early pregnancy examination. Pregnant mothers are often very excited when they hear the "thump thump" sound of the fetal heart for the first time. Under normal circumstances, the embryonic bud appears around 6 weeks of pregnancy, and fetal heart tube beating can be seen under B-ultrasound at 6 to 8 weeks of pregnancy.

However, the time when the embryo bud and fetal heart appear is not fixed:

If menstruation is irregular and often delayed, resulting in unstable ovulation time, which will affect the calculation of gestational age, it may take another week to measure the embryo and fetal heart rate.

The gestational age calculated based on the last menstrual period may have an error of 1 or 2 weeks. Perhaps the fetus in the womb has not grown to the expected gestational age and you need to wait patiently for another 1 or 2 weeks.

In short, pregnant mothers who do not have a fetal bud or fetal heartbeat before 8 weeks of pregnancy and who do not have any abnormal conditions can rest in bed and wait for 1 or 2 weeks before going for a follow-up examination. If there is no fetal heartbeat or fetal bud at ten weeks of pregnancy, it is considered fetal arrest and the pregnancy needs to be terminated.
