Should I be worried about frequent urination and trace blood in urine?

Good day I have a frequent urination problem with episodes of not feeling when to go and sometimes urgency. I saw a urologist end last year. He didnt say much after doing ultrasound he said residual urine is fine. He prescribed Betmiga 50mg I havent started it yet because I'm scared it's going to cause urinary retention. He also found a trace of blood in my urine and said I must schedule a cystoscope in this year which I've done for May. Sometimes I have trace blood and sometimes not. My bladder doesnt feel and look right it seems very enlarged to me however the urologist didnt mention anything about enlargement. Alot of symptoms over the years was or is also psychological Ive been told by doctors and psychiatrist many years back. Should I go for the scope Im scared it's going to make things worst. The blood in urine over years has always been a trace and it is not constant however the last two urine culture tests they found trace of blood.. I am 35 years old male, height 1.63 metres, weight around 80kg. There's no sign of prostrate problems also I had the PSA test done last year.When it feels like I keep my pee in too long even like 10 minutes longer there is a pressure between my legs between my anus and my penis retracts Im really worried. My stools also alternate and put pressure on my bladder and affects the urination. I have been diagnosed as having IBS by a gastroenterologist.
