Welcome monsterinc714!
We are sorry why you are here but, there are many willing to help answer questions. First, your English is better than mine and that is all I know! Yes, low grade is often handled as a "wait and watch/see" monitoring by the doctor. Some additional bleeding often happens depending on how much digging, scraping or burning they do for a day or two. Many of us have very little bleeding, including my tumor which was small. It appears from your post you may have had your TURB during a cystoscopy? That itself is unusual unless you were given anesthesia. It sounds painful!! Tumors are often diagnosed as low grade then found to be part high grade or all high grade upon a second TURB or path, so a second opinion would give you peace of mind. Most importantly you want to find out why you are still passing blood and in itself would get me to a second look.
Keep asking and posting, someone will usually be around to help.
