Yasmin pills as emergency contraceptives

Really urgent help needed! Yesterday me and my boyfriend had unprotected sex for the first time and he's only 95% sure that he came outside but I want to be sure Im not pregnant so I took 4 pills of yasmin pills 30 mins after sex.
 In my research, people said they took 2 doses of 4 pills every 12 hours. Does anyone recomend i take another dose of 4 yasmin pills after 12 hours?
Also, i got off my period 2 days ago. That means I'm not fertile as we had sex right?
