Now, bloody semen. could it mean theres hematuria?

Unlikely: It's unlikely for the blood in your semen to be due to hematuria unless you also urinated blood just before ejaculation Usually blood in the semen comes from the epididymis/prostate/urethra and not the bladder although since urine and semen both pass through the urethra it is not impossible for a little blood from the bladder to find it's way in the semen.

Constant hematuria: If you have no urinary tract infection, you need go to a urologist to assess your urinary tract. You will need a renal ultrasound and probably an intravenous pyelogram to see if there are any problems with your kidneys. If these studies show no problem, you will need to have the urologist do a cystoscopy so your urinary bladder's wall can be visualized to see if you have any abnormalities there. ...Read more
