I have the urge to urinate and then when I go it s a very little amount, almost nothing, but I just noticed there is a bit of blood in my urine. I also have this sort of pinching dull pain in my urethra (I assume it is my urethra). I haven t had a bowel movement in 3 days. I had quite a bit of sexual intercourse over the last few days after not having it in months. There are so many things to me that I could assume is causing it, the pain is tolerable, just uncomfortable but it is the blood in my urine that has me nervous. Should I go to the ER or wait until tomorrow and go see my regular doctor?
