Would a girls period show in the test??

Imma dude, and i took a piss test yesterday cuz i prolly got the dirtiest urine this side of da world... so i went macguyver and used substiute piss, but the only people i could trust is my mom and sista... mom dukes wont havin it, so i used my lil sista piss... she had just got off her period the day befo, will this have any negative results on my test, or they aint looking for that type of thing??? i thought i was scott free, then my gurl hit me wit dat bullshyt, sumbodi please make my hopes reality....

I doubt it unless its red or has a big ol clot in it? LOL
labs are bound down by regulations and protocols which dictate what they can test for and what not. Labs (US) are only allowed to test for drug metabolites and check the Ph, specific gravity, creatnine and excessive nitrites.
