If you don't have the money for an at home drug test I'm afraid there is nothing anyone here or anywhere else on the Internet can do for you except give random guesses. You will find none of the regulars here offer guesses, there is no sense as there is no way for anyone to know if you are clean or not. It is too late to load creatine at this point and since you don't know if you are peeing hot or not to begin with there really isn't much to coach you on as far as dilution goes. If you think you might be hot you would want to substitute. Since you haven't the funds for synthetic you are pretty much left to finding someone you know who is clean. Man, woman, child... Good luck.
