Trying to Stay Calm

I took the Harmony test when I was 12 months, and it came back inconclusive. So a week later I took it again and it came back low risk for for NTD, and that I am having a boy. Well last week I went to my OB and she said I should take a NTD test, I thought nothing of it, since I already took one. but my OB called today, and left a message, right before she was leaving for the day that she has my test results. I know I should be calm, but her calling leaving a message is making me worried again. I just don't get why would my OB call for important information as she is leaving for the day. It is driving me crazy to wait until tomorrow.
