Don't be surprised at the color of your semen for the next couple of weeks after a biopsy. It is a dark primer red color but others may describe it in many other ways. Be sure to prepare your self and your partner before the "next time". Lay out some towels to protect your sheets.
Yes the waiting begins. Everyone here with PCa knows the waiting routine very well. It never stops even after treatment. Wait for another PSA test, wait for recurrence, etc. etc.
I have had UTI several times, not fun.
Good luck, hope you are just visiting us for now.
