I am a male using a woman's urine to pass a ETG plus 7 panel drug test, will her being on birth control be a factor?

No, but it will raise flags when tested..
Here's a thought, STOP drinking and do the test lawfully.

So I will assume you had a heater on your body to keep it heated to the proper body temp.
Since if you just had it in a baggie or bottle in your pocket, it will fail the test when taken, since they do a temp of it prior to sending it to the lab.

I will say that I have given urine to my ex many time for his drug tests... he had no problem keeping it warm enough... and it was not direct observation... just the blue water thing... however... getting caught could have worse consequences than a dirty test. And if it is not the right temp they will make you wait till you can urinste for a retesreg or call it a failure to test.

Oh... and birth control is not tested for so it would not be detected at all as it is hormones which all people have at various levels.

Hope she's not actually pregnant.
