2 weeks still bloody (red), now yellow semen

What could be the problem? there is abdominal pain and testicular pain. Since October 2020. ultrasound, breeding okay. bloody and yellow semen is about 4 weeks old, there was no such complaint until then. tumor marker negative, afp, ldh, hcg. I am 30 years old. prostatitis said the doctor, I took antibiotics, sufixin and augmentin duo. I haven't been taking any medication for 4 weeks. there was an example that both semen and urination were pinched. testicular cancer? hiv?
