Hi, Thanks for posting in HCM. I understand your concern. What symptoms you are complaining of are side effects caused due to taking of prescribed medications. You have been prescribed with hormone progesterone preparation, which would cause certain symptoms like headache, shortness of breath and chest discomfort due to water and salt retention. Another medication contains Clomiphene, which could cause diarrhoea. Clomiphene acts as an ovulation inducing agent and helps to regularise ovulation process. Progesterone would help in progession of pregnancy if conception takes place. Kindly take urine pregnancy test if the periods are delayed by a week to know weather you have conceived or not. If the periods happen in time, it states that you have not conceived this time. Gradually, your symptoms would subside once these medications are stopped. Hope the information provided would be helpful. All the best. Regards, Dr.Ashakiran.S. MBBS., MD.
