Does bleeding 5 days after taking plan b indicate I'm not pregnant? We did not have sex but I was worried about pre cum on his hands

Here are some... Your described scenario poses an almost zero odd to conceive. Nowadays, all sexually active females should do HPT in a wk after missing expected period and repeat it in another wk if the first test is (-) or still in doubt since none of available contraceptives can give 100% guaranty. Meanwhile, practice high standard of safe sex with diligence and vigilance. Best wishes...
