hi there, your daughter is indeed suffering from UTI and the antibiotic taht she is receiving may not be effective. First of all you need to get a urine exam along with culture and senstivity done to see the senstivitgy of the infective organism and accordingly treated. The blood in urine could also be coming from higher up from the kidney
or the ureter
and so she needs to be evaluted for those as well with the help of an ultrasound
and a KUB to rule out any stone. Before giving any treatment it is important to ascertain the source of the bleeding and pain and then initiate treatment. Give her plenty of fluids and get her investigated. Take care.
