My OG doctor inserted a tube into my bladder to collect urine sample (urinary catheter?) to have a good test of UTI. It was extremely painful when he was doing it, although he told me it should have been only discomfort. There was some bleeding at the end of the procedure. The days after, it has also been burning when I urinate. Is this normal? Is there any chance that the doctor did not do a good job and caused my bladder infected? What makes me worried most is that whether this doctor will be good enough to deliver my baby if he could not do a simple procedure?
