I Had Unprotected Sex With My Girlfriend And She Took

I had unprotected sex with my girlfriend and she took ipill by 23rd hour and den we had unprotected sex again within 72 hours. She told me that she will not get pregnant as she took ipill and it seems sperm/ eggs will get flushed out by the premature periods (due to ipill). Plz note I tried my best not to evacuate inside and I'm very much sure dat I didn't make any mistake. However cld u suggest if any action/ precautions required from my end?
Thanks!
