On my 2 round of SculpSure I didn't feel sore or bruised. Is this normal or should my doc repeat treatment to make sure it works

If you didn't feel any soreness after the procedure, you are one of the few who did not experience as much post procedure soreness.  I would not be concerned at this point.

Most people are not bruised after SculpSure.  Mild soreness is common, but it does not always occur.  I would not be concerned that the procedure did not work just because you did not feel sore.  I'm sure that your doctor told you that it takes 6-12 weeks to see the results.
