TMI. sediment/ tissue in urine

I'm 14 weeks....there's no blood in my urine(not visible anyway), no pain urinating or abdominal pain at all but I have urine with sediment in it and what looked like tissue in it...kinda freaking out but I've read so many different things from cancer to its a type of UTI...I have a Drs appt very soon and I am going to call...I'm also doing a 24hr urine so I'll have my answer soon but anyone had anything similar?!?!
