Talk to Gynecologist on Long Term Period

Till last November, my period cycle was so normal. It occurred every 30 days and lasted for 7 days. Last November it was delayed for 2 months and lasted 14 days. This has happened twice for now. This time I got my period on the 25th of May, almost 15 days late. I was expecting to finish it today as my experience. But it is not stopped yet I dnt have any other symptoms Period flow also normal Only the problem still it is not finished I expect some drugs to stop it and your advice. Thank you so much
