Pregnancy & Mensturation, will have problems in her periods.

Gudmorning ma'am, me and my girlfriend are Btech Student, on 6th june me and my girlfrnd were all day together having a good time after a while we fall into deep romance n during it we done little foreplay (to be more specific) i rubbed my penis on her vagina, & went little oral & we both were wet. She's virgin n we didn't had sex, & even i didnt inserted in her or ejaculated inside her or upon her body. But due to fear i she took i pill on 8th June after 50 hours of the Act.
She always have her period after 12th of every month. I am afraid whether she will become pregnant or will have problems in her periods. Plz ma'am help. And kindly advise what should be done further.
