19 week ultrasound!

Just had my 2nd ultrasound at 19 weeks 3 days today at 12:30. This is our rainbow baby so of course we’re over the moon we also found out the gender! But not even 3 hours later at 3 my clinic phoned me and the nurse said my doctor wants to see me this week right away to go over the results. This is my first baby and I have a doctor appointment already booked for March 13, so of course I’m paranoid now. I feel if everything was good the doctor would wait until the 13 right?! Anyone else get a call right away to see there doctor and everything is fine. Waiting 4 days feels like forever.
