Hi, I have had that happen....usually though while I wait for them to check the images, then they come back and get you to have it again...Now they do the difital mammograms...is this what you had? They do an ultra sound when they see something they are not sure of, something suspicious. Do schedule it as soon as you can though. It may be nothing, but if it is something, early detection is the key...I am living proof of it.
