"my accident happened on the 18th ( he came in me no condom) i within an hour ran out and got take action pill which is generic for plan b . next day i had some light spotting that was dark along with cramps and bloat but nothing excruciating. on the 23rd in the am i started bleeding heavy dark blood . today the 25 th  and i am still bleeding heavy , this has to be my period . so for me it came just 5 days after the accident. my last normal period was 8/12-8/16. so two periods in a month . but i&#039;m not pregnant . so just relax and let the pill work. i am 26 , 5&#039;2 and 145#."
