Making a list helps you remember everything when you get there, how long in hospital, when will you start treatment?  will it be surgery? Chemotherapy first? The big question prognosis. Is it ovarian tumour or total hysterectomy?  
They will give you the treatment plan and what to expect but as we are all different it can vary when they operate, l had unexpected extensive adhesions that took hours  to remove when l had my overies removed last year. 
The speed of everything has probably taken your breath away, but it's much nicer than waiting around for results for weeks, biopsies seem to be taking ages at the moment. 
take care
