Joey's Non Stress Test

This is a copy of part of Joey's Non Stress Test.
I guess it's to see how happy he is being inside me.
According to the nurses he is a very happy little guy.
The wavy lines towards the top is his heart beat,
as he gets moving in there his heart beat goes up.
The little square dots in the center indicate when I
felt him move inside me, so everytime he got active,
his little heart beat got faster. The wavy lines
towards the bottom of the graph are for contractions.
