My gfs dates were 19-22 and she took periods delaying tablets from 16 to 21 and then me and my gf had protected sex bt after I discharged I got to know that condom is torn and my sperm is already inside her and she took ipill within 3 hrs of sex, later that day in night she took one more ipill and next day also we had some protected sex and bt she taken another ipill and after that next day another ipill. So in total my gf took 4 ipill in 4 days and now she is not having her periods. Is it bcz of the pills or she is pregnant, plzzzz answer me?
