I tested positive for Benzodiazapines, can OTC give me a false positive reading?

In a 2 week period I have been taking Omega3 Fish Oil (2 a day @ 300 mg) and Green Tea Hoodia Dietary Supplements. Within a month I've taken Move Free Advanced for joint lubrication and One a Day vitamins. I stopped taking the Move Free and One A Day about a month ago. I was totally shocked that my UA came back dirty as I do not take illicit drugs ever. I barely ever take Ibuprofen for my menstrual cramping. I'm now very concerned because I know that I don't do drugs and this positive reading gives the impression that I do illicit drugs. Please help. I would very much appreciate any insight anyone has to this.
