Is There Any Risk Of Pregnancy If Dronis Is Taken Correctly For Two Months And Had Safe Sex On The 19th Day Of The Pill Cycle?

Hi doctor, My friend who has been using dronis 20 to treat irregular periods and PCOD since 2 months and also continuing the treatment now has undergone safe sex(used condom) on 19th day of the pill in this month (march 2022) . She has been taking the pill continuously without missing the dose. Are there any possibilities of getting pregnant as she is really worried of it. Can you please suggest.
