Hi, I Smoked Weed A Little Over 10 Days Ago

Hi,
I smoked weed a little over 10 days ago (july 6) i have a drug test coming up either the end of next week or start of the following week.. i had a gram, gone in about 5 days. i hadn't smoked for maybe 2 months before this..and when i did it was only twice. but before that i was clean. i'm 5'3 and 220lbs (yes im fat.. working on it) and i've been working out since the middle of june. this week alone i've done about 9 miles. very nervous and getting mixed reviews.
