Thanks for the query.
Usually poly cystic ovaries will cause problems like irregular menstruation
, insulin resistance
But as you are having regular cycles probably you are ovulating regularly.
The medicines give by your doctor mainly contains vitamins and supplements which will help in increasing general strength and fertilizing capacity.
As you are ovulating normally may be because of that your doctor didn't keep any ovulation induction
Ideally your weight should be around 60kgs.
So by decreasing some amount of weight and planning intercourse around the time of ovulation you can increase the chances of conception.
