UTI - *GRAPHIC PHOTOS* passing blood clots, is this normal?

I have painful urination, it was bleeding when I peed last night and then once I started passing blood clots there was no longer any liquid blood if that makes sense. 
I am now passing "chunky" blood bits and I have gotten trimethoprim to treat the infection, Ural and I am drinking water as much as possible. 
Is this normal? Has anyone had something similar before? I have taken pictures but they are quite graphic.
