Since you have irregular periods
, it remains to be seen when you could have ovulated this cycle. In the current scenario, I would ask for a serum beta-hCG titre estimation to definitely confirm/exclude pregnancy
since HPTs cannot be relied upon. If pregnancy is excluded, your symptoms could suggest an impending period. Withdrawal bleeding can be expected about a week after completion of hormonal
treatment. Failure to do so calls for further investigation including a complete hormonal profile, trans-vaginal sonogram and glucose
tolerance etc. Hope you find this information helpful. Take care.
