thanks for your query.
you have missed pills twice in this cycle but you have taken two pills on the next day .if your previous cycle were regular and you had unprotected intercourse
in the last wk of cycle the you are having less chance of being pregnant but to rule out pregnancy
you must get urine pregnancy test or blood hCG
levels done . Delay in cycle could be due to hormonal
imbalace or change in lifestyle.In future you should be more careful and take your pills regularly. take care
