I have been having prolonged periods issues, from past 3-4 years, consulted a gynecologist and she prescribed me T crina ncr, aurtin capsule and corectia-M for 3 months. I have been on crina ncr 10 mg from past one year with the prescription on the same doctor. When I am on meds I get periods on time and for 3 days only if not I'll be having periods with heavy flow for more than 15-20 days. I have PCOS should I stick with the same medications or is it only because of my lifestyle or do I have some other conditions. Tested for thyroid(T3-1.75, T4-11.14, TSH 1.12) normal.
