Unprotected, Ipll & future pregnancy.

1. I had unprotected sex with my girlfriend last November 2018, 10 hours after sex, I gave her ipill or unwanted 72 tablet, she missed her period that month & her period resumed to normal cycle. 2. I had same unprotected sex with my girlfriend second time in January 2019, where I gave her ipill tablet after 15 hours, I think she didn't miss any periods this time. last month april 2019 she had periods bleeding for 10 days then stopped. my question & tension is does that tablets affects her future pregnancy ?? Is there any serious problems for her body & her future pregnancy?? Does she Normally can have pregnancy in future or these tablets which she took affects her future? please clear my doubt clearly & genuinely I mean nothing to hide for my stress. thank you,
