Six years ago when I was dx'd, I had a lot of blood. It was like I was just passing blood instead of any urine. Because it was a Saturday morning, I went to the ER. Thankfully, the ER doctor did a sonogram and the tumors showed up. I am very grateful to that doctor, because I was told by some top Urologists that most ER doctors would just think it was an infection and prescribe an antibiotic.
Two days later I had a cysto and, that was when I found this site.
I understand your worry. Why not call the doctor's office tomorrow and tell them of the heavier bleeding? Maybe he can see you sooner? I am sorry that he had you wait a month for the cysto, the waiting time can seem unbearable.
Good Luck,
Nancy
