My Gf took 4 ipills within a month

I know I'm so stupid, guys, but today we had unprotected sex again. It's just that she's leaving the country and won't be back for three years. So whenever we meet, we lose contro.l.. Now, the thing is, I pulled out before ejaculating, but she's really scared because if something serious happens, her study abroad plans could get canceled. What should she or we do? She wants to take another i-Pill, but I'm trying to stop her because her ovulation period is over, and l pulled out, so the chances are very low. Please, guys, I know this is our fault, but can you suggest something? I'm scared too.
