I want to know if i should be worried about thc still being in my body after taking a few hits from a bowl?

that was all ashes? i got like two or three "ok" hits from it. i have a drug test next monday and i did this stuff last monday and tuesday, for the rest of last week ( wed, thur, fri) i worked out hard for a few hours each day and have been drinking lots of water and taking vitamins. since the thc is in your fat and i worked out those days plus these past few days should i still be worried about the thc in my body?
