The normal fetal heart rate (FHR) during pregnancy ranges from 120 to 160 beats per minute (bpm). A fetal heart rate of 146 bpm is within this normal range， which means that the baby is healthy and has a stable heartbeat. However， individual variations in fetal heart rate can occur due to various factors such as maternal health status， gestational age， activity level， and others.
Maternal health status can also have an impact on fetal heart rate， as any underlying medical conditions or complications that affect the mother's health can affect the baby. Gestational age is another factor that can affect fetal heart rate， and as the pregnancy progresses， the fetal heart rate tends to decrease slightly.
The fetal heart rate can also vary based on the baby's activity level， such as being more active during the day and less active at night. In addition， certain external factors such as maternal stress， physical activity， and medication use can also affect fetal heart rate.
However， in general， a fetal heart rate of 146 bpm is considered normal and healthy during pregnancy. It is always recommended to regularly monitor fetal heart rate during pregnancy through regular prenatal check-ups. Your healthcare provider can evaluate your baby's heart rate and make recommendations if there are any concerns or if any issues arise.
Overall， a fetal heart rate within the normal range is a good indicator that the baby is healthy and developing well. However， any concerns or questions about fetal heart rate or any other aspects of your pregnancy should be discussed with your healthcare provider to determine the best course of action.
