Stomach/Bowel cancer symptoms?

Hi, I've been having blood in my poo for a number of years which the doctor always put down to ibs, which has recently got worse. But this year I've been constantly exhausted, feeling sick, stomach pain & bloating, back pain, stomach constantly making noises, indigestion & acid reflux. I also feel like when I eat the food gets stuck in my throat. 

I got bloods taken & the only thing that showed up was that there was something wrong with my kidneys & I've to get my bloods done again in 3 months. 

I also did a fit test that showed blood in my stools & was referred for a colonoscopy which came back clear, but they took biopsy's just to be on the safe side. I'm still waiting for the results of the biopsy's.

I'm also waiting on an endoscopy. 

Has anyone else had these symptoms & if so what was your outcome? 

My Dad died with stomach cancer at the age of 49
