HER2 FISH Results timeline

I was diagnosed with IDC Grade3 HR/PR+ on Monday. I have been followed by a high risk clinic for four years due to a previous wide excision for PASH. My last mammogram in October of 2021 was BIRADS 0.
Tomorrow, I will go for an MRI and bloods for staging. I have been told that the HER2 FISH could take weeks due to staff shortages. How long did you wait to receive your HER2 FISH results? The lesion, as viewed by sonogram,is currently, 3.7 x 2.5 x 2.2 cm. Guessing that this will stage at IIAor IIB
