another problem

So, I did the SWF (Salt-Water-Flush) for the first time yesterday. And since I did that, aout an hour later I started seeing blood in my urine. Don't know if it is related to that. I got my period about eight days ago, and it ended 4 days ago, so I don;t think it is related to that. I thought it was just a one time thing, but now it seems to be getting worse. Does anyone know what has caused this and if I should be worried??

Thanks
