There isn't a straightforward answer to this question because the fetal heart rate can vary greatly from one pregnancy to another， and it's dependent on several factors. However， there are a few things we can say about fetal heart rate during pregnancy.
Typically， during the first trimester， the fetal heart rate ranges between 90 and 110 beats per minute. As the pregnancy progresses， the fetal heart rate increases， peaking around 170 beats per minute at 9-10 weeks gestation. After that， the fetal heart rate gradually decreases again until birth， where it ranges between 110 and 160 beats per minute.
There are several factors that can influence the fetal heart rate during pregnancy， including the baby's age and activity level， the mother's health， and any medications or interventions used during pregnancy.
For example， when the baby is active， the fetal heart rate tends to increase， whereas when the baby is sleeping， the fetal heart rate decreases. Additionally， certain medications or interventions can affect the fetal heart rate， such as pitocin used to induce labor， which can cause the fetal heart rate to increase.
While there isn't necessarily a correlation between gestational age and fetal heart rate， there are certain conditions such as fetal distress or pre-eclampsia which can cause an abnormally high or low fetal heart rate. In these cases， it's essential for healthcare providers to monitor the fetal heart rate closely to ensure the well-being of the fetus.
Overall， while fetal heart rate can vary throughout pregnancy， maintaining optimal health， regular prenatal checkups， and careful monitoring by healthcare providers can help ensure normal fetal heart rate patterns and a healthy pregnancy.
