I can see blood in semen, is that a orchitis symptoms? I have been diagnosed with orchitis 6 months ago.

Symptoms of orchitis are similar to those of testicular torsion. 

These can include:
ejaculation of blood
hematuria (blood in the urine)
severe pain
visible swelling of a testicle or testicles and often the inguinal lymph nodes on the affected side.
