Is Pregnancy Possible Despite Taking Yasmin Pill?

Hi doctor, I and my wife have sex 2 days ago, we use durex as condom. I think I already cum, but she keep moving. I am afraid if the sperm leaked from below. We couldn t find EC here in our place , I already asked every pharmacy in this place. My friend who are a student in medical, told me to use yasmin as EC. he told me to to give my wife 1 pill every day at the same hours. So i told my wife to take it every 9pm, it s already 2 pills until now. Does ysmin can be use as EC ? Please tell me the right dosage, until now it s already 36 hours after we have sex. Thank you.
