32 days clean and still testing positive?

Im a long term heavy marijuana user. I haven’t smoked in 32 days and am still testing positive on multiple at home drug tests. I had smoked probably a half gram of wax during my last week of smoking as well as flower. During my time clean I have drank a lot water, light exercise 3 days a week, took a 7 day detox program a few weeks ago, and a cup of coffee every morning. I haven’t been eating as much as I used to when I smoked, but I do tend to eat kind of fatty foods. I’m also pretty skinny with a fast metabolism. I’ll be taking a drug test in a lab sometime this month. Should I be getting worried? Do you think the wax just caused me to have insanely high levels, and that’s why I’m taking longer to get clean? Are the fatty foods I eat causing the thc to stay in my system longer, despite my fast metabolism? Sorry for the long post, just want to provide as much info as possible. So what do you think I’m doing wrong? What should I do to get this THC out of my system ASAP?
