2ww following ultrasound, Hysteroscopy tomorrow

Hi,

I'm very new to this, I'm mid 40's premenopausal and not peri according to my GP. After speaking to various GP's at our surgery due to abnormal bleeding, always been like clockwork, suddenly went haywire, bleeding in between and for a couple of months and heavy. She sent me for an ultrasound last week, had a call from GP with 24hrs, said cysts on ovaries and a patch of thickening in my uterus. Refereed me via 2ww, same afternoon the hospital call to book hysteroscopy, which is tomorrow.

My immediate question is that I've started bleeding very heavily again today, will they still be able to do the procedure does anyone know?

thank you Dott
