Hey man, I would probably not worry about it if I were you. From your body description you are most likely fine. 76 days is plenty of time to pass a urine test. I have been worried too, took a urine test after 62 days clean and passed multiple at home tests during the time leading up to the test. I think you'll be ok... I totally get where you're coming from tho... It's hard to not worry about it even if you should be ok. Let me know how it goes
