Hi, my newborn baby girl, 10days old, has blood in urine. Have taken to local gp for advice, but really didn t know why. I asked if she needed to take swab for test, which she did and she said she would let me know if she finds anything. My baby seems to be sleeping alot and I try to wake her for feeds but she doesn t want to wake or feed, she s now had two 8 hr sleeps in past week and can sleep 4-6 hrs. Is it related to blood in urine and how long can bleeding last if nothing detects in test from gp.
