I've been back and forward with my doctor for a few weeks now with my 3 year old daughter having sharp sudden pains in her stomach, they did a urine test and came back UTI, doctor gave her antibiotic. This cleared up and she still had the pains, was asked to do another sample, this one came back normal, doctor prescribed her another antibiotic even though no infection. Dad noticed blood in her urine yesterday and blood in urine today. Took a sample in this morning and heard nothing back all day. Is it normal to worry so much? My brain convinces me there's something more to it. She is absolutely fine otherwise, eating, drinking, playing, sleeping, and is absolutely fine in-between pains.
