Did I substitute properly?

Hello!

I just got back from a pre-employment test. I substituted with my wife's urine (who may be pregnant, don't know how relevant some think that may be), but didn't have quite enough to fill the line. I topped it off with maybe two tablespoons worth of my own urine. (Which, I had been diluting since 5 hours prior just in case I had to do so.)

If I am past the 50mg THC cutoff, would that be enough to test positive, despite the large majority of the urine being hers?

Could anything conflicting show up on the test results by combining urine from two different people?

Should I have anything to worry about?

Thank you all!

Gender and pregnancy are not tested in urine samples collected for a drug test. So you have nothing to worry about there.

How much of sample (in ounces) did your wife give you to sub?
