As per your history, you seem to be having very scanty menstruation
and ovulation status has not been established. It is likely that you may have had a prolonged amenorrhea
this time. Pregnancy needs to be excluded, though, by a blood test
and a trans-vaginal sonogram performed to see for any local causes. To correct the system, you should have a complete hormonal workup along with blood counts and urinalysis
and appropriate treatment based on the cause. Empirical treatments would do more harm than good. Hope this information helps you. Take care.
