Oh you poor thing!  the problem is no one can really answer that unless they are a medical professional. My mum was fine on Monday and went to the pub and then died on Wednesday suddenly from cardiac arrest  possibly from some sepsis and other things caused by her cancer all through her body.

It does sound like your poor dad is very poorly though and I would spend every bit of time with him possible.  No one ever regrets spending too much time with a loved one who is dying, but there are plenty who wish they had spent more time.

Just be there as much as you can, talk to him, comfort him. My friend lost her dad earlier this year and she was a nurse and even she didnt know her dad would die the night he did. but she spent all the time looking through old photos and talking about her childhood.

thoughts are with you in your dark hour xx

hello, when my dad was on end of life care i googled the sypmtoms every day and did a mental check list of what he had and what he didnt have this helped me loads to understand what to expect what to look out for, and even tho i wasnt with my dad when he passed he passed with a night nurse there in his sleep with a smile on his face, ( he wouldnt have gone with us there) i knew it was only a matter of time before he left us.. 

nothing can fully prepare you tho ..
