Without examination, it is difficult to say that your symptoms are "normal" or not. It is certainly possible given the scenario that you described. The procedure of placing the stent as well as the stone itself can lead to continued discomfort and hematuria. It is also possible that discoloration can continue until the stone is eliminated.
Regarding the discomfort, you may want to discuss with your urologist whether the stend is causing the symptoms.
Followup with your personal physician is essential.
