I Have Stopped Using Marijuana For Months Now And My

I have stopped using marijuana for months now and my levels are not dropping and in fact my thc/creatine levels increased according to my last ua. I have been trying to do the rich things by eating better, being more physically fit, and drinking more water instead of other fluids like coffee and soda but now this. Why would my levels increase now? I am at a complete loss and I don't know what to do.
