Oh, that's good that you will get the results right away. I had to wait 7-10 days for my u/s results.
I'm sure everything will come back just fine. I had all sorts of pains in my abdomen for months and finally went to have a few ultrasounds done. Everything came back completely normal after I had self diagnosed myself with ovarian cancer, pancreatic cancer, intestinal blockage, you name it. Oddly, after I got the news that things were normal, the pains went away.
Our minds are very powerful.
Post back with your results. Everything will be fine. :)
