First, don't panic! Blood in the urine is quite normal and also blood in the semen for several weeks. It cleared out of my husbands urine first after a week or so but took longer to clear out of his semen. I think the anxiety of waiting, like you said, is the worst part of anything, biopsy, surgery or whatever. It will clear out, just give it time.
