Blood in the urine is NOT normal. If the symptoms you mention - pain, bloody urine and constipation - persist, you should go see your health care professional. In the meantime, keep yourself hydrated by drinking both the water and lemonade and switch to the senna leaf tea - Smooth Move or Get Regular - in the mornings and evenings. You are not supposed to take any pills, medications, vitamins, mints, etc. during the cleanse, including laxative pills. The ingestion of anything but the lemonade will cause digestion defeating the purpose of the fast.
