Possible UTI?

Hi, for the past 3 or so days I noticed I have needed to pee 24/7, even after I’ve been I need to go again, very little comes out and it seems to have little white particles in it which I don’t know if that’s normal? It’s definitely worse today than it was a few days ago, it feels stuck almost? But I haven’t had ‘pain’. This could just be my anxiety playing up but I’m not sure.
