Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Return of ovulation is observed in a couple of months after terminating oral contraception. This is the most likely reason for the delayed cycle. However, as your cycles are no longer protected, it is important to check for the possibility of conception, in the event of early ovulation. I would suggest a proper clinical evaluation and a pregnancy test. Further management can be planned accordingly. Hope I have answered your query. Let me know if I can assist you further.
