Worried.. (long post)

So last Monday 4/30, I had a baby appt in which my dr toke blood out to do the NIPT (noninvasive prenatal testing). They said I would get results in about a week. Well today, 5/8, my dr called me and asked if I can reschedule my appt from 5/29 to sometime this week or next. So my new appt is next Monday 5/14. My question is, is this normal? Should I be concerned about the test results? I know I should have asked if everything was okay since we’re rescheduling for a lot closer. But when we were talking so many things were going through my mind I couldn’t think to asked then. 😞 has anyone experienced this? I seen my baby just last week and the dr said it was healthy and growing as normal. I am currently 12 weeks as of today. I just don’t understand.. I’m a FTM so I don’t even know what to think.
