Anybody having issues with sediment in urine?! TMI picture

I've had this white tissue like stuff for over four months now and sometimes it's red looking I've been to the doctor and they swear it's okay they've tested it and there's no infection. But I'm still freaking out. I've never had sediment in my urine and the reddish or pink looking stuff is freaking me out. I'm not pregnant and I have PCOS it's really the only thing I have. Any ideas? TMI picture sorry ladies I'm overly paranoid lol
