Welcome to Healthcare Magic forum.
Menstrual abnormalities are common in women of your age group. Irregular periods
commonly result from anovulatory cycles ( during which ovulation does not take place), endocrine disturbances and a variety of other causes. Since you do have insulin resistance
, I would suggest that you get yourself screened for PCOD/PCOS again as these conditions are associated with PCOD. Stress
can be a cause of menstrual irregularities occasionally. However, it would be best to see your gynaecologist if your symptoms recur.
