I Took One Hydrocodone 5-325 Last Night At About 7

I took one hydrocodone 5-325 last night at about 7 pm for a tooth abscess. I was called in for a job interview today at 2 pm. they did a urine test and it showed positive for mo... something but she is going allow me to take another test at 9:45 am tomorrow. ..she told me to drink a lot of water and cranberry juice since it was only one pill do you think i will pass? Or should i say how long does one pill take to exit your system? Thank You.
