During pregnancy, the fetal ventricle needs to be monitored, but the fetal heart rate does not appear at the beginning of pregnancy, but gradually appears during the pregnancy process. Therefore, after the fetal heart rate appears, it should be monitored at different time periods to observe whether the baby's development is normal at any time. So, how long can the fetal heart rate be measured during early pregnancy examination?
If it is under normal circumstances, fetal heart rate should be visible at 7-8 weeks of pregnancy. But it cannot be ruled out that some people may conceive later, so it is normal for fetal heart rate to appear after 8 weeks. But if the fetal heart rate has not been seen by more than two months of pregnancy, it is necessary to undergo a detailed examination, and it is very likely that there has been fetal arrest.
So when is it better for both babies and pregnant women to undergo fetal heart rate testing after the occurrence of fetal heart rate?
Firstly, self-monitoring of fetal heart rate is not allowed before 15 weeks of pregnancy. If you want to test fetal heart rate between 15 and 28 weeks, you can do it at home. Generally, you need to test it three times a day. If each test lasts for one minute, it means it is safe.
Secondly, after 28 weeks of pregnancy, as fetal differentiation is complete, the time and frequency of fetal heart rate testing can be extended.
