Fetal heart rate?

According to web information, fetal heart rate has the following characteristic:

At about 5 weeks gestation, your baby's heart begins to beat. At this point, a normal fetal heart rate is about the same heart rate as the mother's: about 80-85 beats per minute (BPM). From this point, it will increase its rate about 3 beats per minute per day during that first month.
By the beginning of the 9th week of pregnancy, the normal fetal heart rate is an average of 175 BPM. At this point it begins a rapid deceleration to the normal fetal heart rate for the middle of the pregnancy of about 120-180 BPM. (Information source here)

So last week, we tried to detect our baby heart rate by a heart rate monitor.

Polar is good at heart rate monitoring.
Of course, our test has a lot of limitations, not to mention error and interference, but it seems that the watch can detect some heart beats.

It should not be Stephanie's heart beat, as it is too high. What do you think?
