<s>[INST] Am 31 years old and trying to conceive. I have hormonal imbalance and pcod for a long time. During this time I was on dronis30 to regularise my period and as a contraceptive. Now that i want to conceive mu gyny has given me oosure, thyronorm, folic acid regularly and duphaston from the 15th day of my period for 3 cycles. Up to which day of my period should I have duphaston? He has not specified. I have had it from the 15th day up to the 28th day. Is it correct? Should I stop it now and wait for periods? If I don t get periods am i pregnant? Kindly explain asap as my doctor is unavailable now. [/INST] Hi,I read your query and I understand your concerns.Following is my reply:1) Duphaston is a progesterone which is important as progesterone support.2) It can be taken for 15 days after ovulationLet me know if you have anymore questions.Regards,Dr. Mahesh Koregol </s>
