So i started my period march 12 and it stopped the 16th, on march 22 at around 12 a.m  my boyfriend and i had unprotected sex, and he pulled out as he was about to cum yet he didnt really aim right and i felt some go to my vagina, and so the next day around 4-5p.m we went to walmart to get the plan b pill, i took it but 10 mins after taking it.. I threw up.. So.. He went back to get another one, but i ended up taking the other one at around 11p.m... What are the chances of the pill not working... Im scared..
