Calm my nerves please

Virginia
Suffered a missed miscarriage at 18 weeks in sept I got my bfp at 9 days past o this month I am 5 weeks today I have had a doc confirmed urine test and I had blood work drawn to have my hormone measured they said they would have the result that day to give us a number to see how far along I am and I am scheduled for a scan on Jan 5 at 6 weeks bc I'm high risk.....but what I'm scared about is that the doc hasn't called with my result ...I have called twice and been forwarded to that doctors nurses voicemail I have left messages twice.....in the last two days...should I be worried that I haven't heard a response ...are they trying to wait and tell me the bad news in person? Why wouldn't they tell me
