Hi,Welcome to Health care magic forum. The reason for the irregular periods may be the anemia, or infection. After menarchy, for few months it may be irregular.Or there may be some structural abnormalities, like fibroids. I advise you to consult a gynecologist for diagnosis and treatment. You may need to have an M.R.I. for diagnosis. I usually prescribe hematinics, fluconazole, and cifixime. Fenugreek is used for several ailments, but there is no proofs for any thing.It can be used based on belief, and belief can bring any results. Wishing for a quick and complete recovery. Thank you.
