Ultrasound with no success~

I had an Ultrasound done on the left breast being they found a suspicious mass on that side with the MRI.  Needless to say, they did not find anything in the ultrasound.  Now I have to wait yet again till next Thursday and have another MRI with a biopsy this time.  Orders something from the doctor so I wouldn't be so queasy in the tube this time.  So we wait.~
