So i had sex one time & we used condom & it didn't break. Like 30 minutes later we had sex again but this time no condom & he did not cum on me but i was worried that maybe he had some cum in his urethra from the last ejaculation so like 12-14 hrs later i took an emergency contraceptive & yes i know i can't be using it as a normal birth control. By that date i wasn't even on my fertile days, my fertile days started 5 days after & my ovulation date like 10 days after that day i had sex. Is there a high chance the emergency contraceptive could fail on me?
