Hello and welcome.... The waiting game is a very nervous time indeed. We have all been there and know the tension of waiting for an exam or test results. One of my pet peeves is how often doctors ignore or downplay blood/clots in urine for women since that is just "something we do" normally and just write a script for antibiotics. It is good news that your kidneys show no problem on your CT scan.
I don't want to second guess your symptoms since the cystoscopy on August 2nd will show what is going on inside your bladder. I know your head is spinning at top speed at the mere prospect of bladder cancer. Just remember that if it were to be so, it is very treatable these days and a top-notch doctor is crucial. Just so you can be prepared, if he finds something suspicious, while you're waiting research some hospitals and their urology departments in your area and ask him for a referral (if your insurance requires it) of your choosing for a second opinion (unless your uro is one of those specialists, but a second opinion is always encouraged anyway). If you tell us where you are, we can probably suggest some for you to consider.
Also, if the cystoscopy shows nothing a trip to your gynecologist is needed. My gynecologist actually found my bladder tumor. I went to her first because she told me on my first visit to her that "any bleeding after menopause is NOT normal and needs to be checked immediately" so I went straight to her when I saw that little tinge of blood on the bath tissue. All the female stuff was OK, but upon seeing that small mass in my bladder she sent me straight to a uro. Prior to that, I had never even had a UTI ever so going to a uro had not occurred to me!
Please continue to ask any questions you might have or join in discussions on other threads. I hope your cysto goes well and the source of your symptoms is found quickly.
