Hi everyone

I just was discharged from the hospital with hematuria (blood in the urine... see picture below) and I have an appt with Urology on Wednesday. They checked and said the bleeding wasnt coming from the cervix or vagina itself and they monitored the baby and hes doing healthy and great. But they're not really sure the cause of the bleeding. They ran urine test and tested for infections too but nothing really abnormal showed up. Has anyone had blood in their urine? And not just a little but alot? I'm 30 weeks 1 day. Just curious. I know baby is healthy and so it's not from him.
