How horrible to be worrying so much, I do empathise. Please try not to let your mind think the worst, the facts are that the likelihood of action needed from your test is minimal and even more so as the lady reassured you that if there was a problem etc etc. I know that having the result in your hand or told to you is what you need and until then will likely worry, but try to put it in a box for a bit so you don't create so much anxiety for yourself.
I have felt exactly the same when I had a cervical polyp removed a couple of years ago, that I had avoided removal of for well over a year. The result was longer than expected, I was then told on the phone a letter was on its way to me, she couldnt say anything but hinted all was well. I was swinging between reassurance and excrutiating worry until the letter arrived and I had the all clear.
You will get through this and I hope it will be tomorrow when you hear x
