What is going on in there?!

L
I'm pretty sure there should be more movement in the thurs trimester and I even read that it becomes more regular on a schedule as they develop REM. But this little jumping bean has been going at it for two days! What is she doing? Somersaults with round house kicks finishing off with a one-two punch??
It's getting painful! 
Anyone else experience this much movement? 
I'm 30+5 today...
