I’m 8 weeks pregnant, i went to the er bc i was having severe back pain. They couldn’t find anything wrong with me (they did ultrasound on kidneys and bladder to check for kidney stones) and they inserted an infant sized catheter ( my urethra is abnormally small) to get clean urine. They only left it in for a minute, i just got home and peed and there was sooo much red blood. It almost looked like a period. That isn’t normal, is it? They kept pressing on my lower stomach too and it hurt so bad i screamed, but they sent me home not knowing what was wrong.
