Natera testing?

Jasmine
Okay I got the natera blood test done last Wednesday and I know it take 7-14 days to come back but I have been seeing where everyone gets their results online... I was never given a lot code or case number or whatever it is called from my doctor so after making an account online I couldn't sign into anything because I didn't know any of my stuff. Does that mean my doctor will call me with my results or am I supposed to call my doctor to get a kit code? I'm just wondering so when the results are back I can actually know what they are. Thanks!
