I'm Only 22 Years Old 23 Next Month And I

I'm only 22 years old 23 next month and I believe I have hematospermia. My semen have a reddish color to it when I seen it. I'm not experiencing any pain and there is no blood or discoloration in my urine. I figured I should wait a week before going to a doctor to see if it goes away on its on. Should I avoid any sexual activities for the time being or could this be more serious than I think?
