i had my girlfriend take both pills.

So i had sex with my girlfriend on tuesday, and the condom broke. Obviously concerned, i took her straight to rite-aid and bought her next choice. At the counter, both pharmacists recommend that i have my girlfriend take both pills simultaneously. She took the pills ca. 20 minutes after intercourse. According to her, she was two days off her period when we had sex. I'm pretty young, and a pregnancy could throw some real bumps in the road. help?
