Hi there i understand your concern... You should continue medications for few more months to see significant change....You should decrease carbohydrate intake, take foods made-up of whole grains like whole wheat bread,
Decrease fat intake and increase protein content.
Take high fiber diet, fruits, vegetables but avoid starchy vegetables like potatoes.
Take plenty of water avoid
sugar drinks....once the cycles regularised you can try for pregnancy... Consult nearest gynecologists they will do the needful.
