It is recommended to use a back up contraceptive method during your first month of taking Oral contraceptives, especially the first week.After the first week of Oral contraceptives, the chances of pregnancy diminish. In your case I would suggestion to keep taking your medication and wait for the end of your cycle for your menses. If they dont show for a week after your due date, you might want to take a pregnancy test to rule out pregnancy definitely. Sometimes your oral contraceptives could also alter your menses due date. I wish you the best.
