Dear jabeen tallat
You have not mentioned about any investigations conducted and to reach at proper diagnosis at least ultra sound

To induce periods you can opt for herbal medicines insead of hormones. Amongst herbs seeds of carrot are used to induce periods. Amongst medicines for symptomatic relief Nasht Pushpantak ras or Rajha pravartini Vati can be taken. Permanent cure calls for proper diagnosis.
