Unclear question: I think you are asking if you could be pregnant. If you think you might be pregnant check then check a home pregnancy test. They are cheap, reliable and available at any pharmacy. Sometimes people skip periods when taking birth control pills. This is not rare. If the pregnancy test is negative then you simply continue taking the pill.

Possible reasons.: Reasons for missed /late periods: low body weight, obesity, marked weight gain or loss, over-exercise such as in endurance athletes, breast-feeding, stress, illness, eating disorders (bulimia or anorexia), travel, hormone irregularities, drug use, medications (i.e., birth control) or med problem (polycystic ovary syndrome or Asherman’s syndrome. #1 reason for missed period is pregnancy.
