Can I Continue Taking Duphaston From Day 14–28 Of My Cycle, When I Missed 2 Days And Started Bleeding On Day 25?

Hi, please am on Duphaston medication, I have taken it for 2 month s and this is the 3rd and last month . According to the prescription I take duphastone from day 14 -28 of my monthly cycle (14 tablets in total)This month I took only for 8 days , 8 tablets and i have skipped 2 days, due to unavailability of drug. Please can I continue as I now have the drug? But already experiencing a bleeding on the 25th day of my cycle instead of 28 days. Note am not pregnant. Thanks
