I had a vasectomy now have blood in my semen (seminal fluid), will it stop?

I am 65 yr old i had a vasectomy 40 years ago. And about 3 yr ago I had blood in the semen. A urologist gave me Procar 5 mg and it slowly stoped after 2 1/2 years. Then it was just a small amount of clear flood, and now it has a tint of red in the flood. I did not think the Doctor took it very seriously. Will it just go away in time? thank you.
