Possible deafness?

Kate • deaf nurse with a bad attitude. momma of two, wife of almost 7 years to the love of my life.
I'm 26 weeks even today, and went in for an appointment. The tech noticed she isn't moving at all to the sound of my voice, laughter, or loud noises. We tried playing music against my tummy and again, no reaction. They gave me another appointment for two weeks from now to see if she's just ignoring her surroundings or possibly deaf/hard of hearing.
Has anyone else experienced this with their little ones? I'd be lying if I said I wasn't terrified. I have no idea if there is even a process to check for this or if we have to wait until she's here.
