thank for using healthcare magic,
well by circumstances which you discribed its very difficult to get pregnant just by fingering contaminated with semen plus you took i pill
so chnaces are zero..
you also got your period after that so its not possible that you are pregnant..
this month delay can be some other reason like stress
, heavy physical activity , exercise or hormonal
i will suggest you to wait for few days and still if you dont get your periods then consult gynecologist..
