It sounds like she maybe having the GC test done. If she is then it wil be tested at the 15ng level.
A word to the wise,don't tell your PO what prescription drugs you are taking. If they are legally prescribed drugs you can tell them after a test comes back. In your case neither of these drugs would have showed positive on a 5 or 10 panel standard drug test. But because you told her about the prescription it looks like she has ordered the GC/MS test which is harder to beat.
You still may have 2 things going for you. It still maybe dilluted enough to pass and if this is the first test and it ends up positive tell the PO you smoked about about 2 months ago.
