Genetic ultrasound HELP!

My wife has her genetic ultrasound on Thursday, but the dr just called and had to cancel it due to an emergency. My wife is so busy at work she doesn’t have another day to reschedule. This test can only be done in the first trimester and Sunday she will officially be in the second. We tried asking if we can go to another Kiaser for this one appointment, but they said no since we are getting prenatal care there. We don’t know what to do please help with advice. Thank you.
