Thanks for the query.
Usually the menstrual cycle will become regular while on pills but when you stop the problem can recur.
If you are having heavy bleeding now, better to take tablets like antifibrinolytics
to stop the bleeding first.
Then in treatment of PCOD you can go for insulin sensitizers along with hormonal
Better to decrease the weight in case of overweight
which will increase the response to treatment.
Though PCOD can affect the fertility
to some extent there are treatment options available to tackle the problem, so don't worry.
