After 2 months either you're not telling us everything or the test kit was defective. Can't imagine you would turn up positive after 60 days...unless you're, how to say this delicately, a big person. The more overweight you are the longer it takes to clean out the system. A friend of mine who's a good 40 or 50lb overweight took about 45 days before he tested clean on a home test.
I am 5'8" and 145 with a fairly high metabolism and was able to test clean in under 30 days.
