Thank you for your query.
PCOS is a condition that frequently causes anovulation
, and as a result irregular and delayed as well as scanty periods.
As you did not respond to clomiphene
the first time, the dose might have been increased this time.
In case there is no response to higher doses of clomiphene, you might need higher order medications in the form of gonadotropins and injections etc to produce ovulations.
Also, weight loss
, diet and lifestyle modifications are an important part of PCOS treatment.
You might need metformin
to get better results.
CONsult a fertility specialist at the earliest.
