Walk into a drug store purchase one and ask to use there bathroom and take the test , results in minutes .. Then you will know and the test will be tossed in there garbage can, walk back out and buy some candy and go back home ... No one will be able to figure out what you did ... Just as Hamster said people have enough stuff of there own to give a hoot bout you go to a drug store.

Simple solution .

I wish you the best.
