Laura, I called. But keep in mind, the weekend does not count for them. The sample has to be sent out, and the path report dictated, signed and sent to your doc, then read by the doc before he calls you.
I had to wait nearly 2 weeks for my lymph node results. WHen i got to the day that they said it might be in, and still no results, I was a nervous wreck. the next day I called, and the nurse did read me preliminary results. I was surprised she did so, but thrilled.
Try to assume that you will not get results tomorrow either, so you can try to relax. And on Wed, maybe call by the afternoon if still no word. Unfortunately, these processes take time, and the waiting is the hardest part.
