I don’t know so I will call them , but too scared to call

Oh dear, that is a horrible feeling. I totally understand that. 
When I was called from the bread unit yesterday I got worried. 
but it turned out that it was the receptionist and she said she didn’t know anything about results so could only say the appointment needed changing because of a backlog in the lab. 
I expect if you call you will have similar answers that they don’t know anything about your result, and will at least tell you what to expect. 
such a horrid waiting time, 

I hope you’re managing to do something nice with your son.
