im having the same issue with irregular periods, no psych meds anymore, no formal diagnosis of pcos, tho my doc seems to have latched on to the mention in the file... im obese, and have had irregular periods my whole life but not THIS bad.. im on 36. i do have hypothyroid. so lots of things potentially. but my pcp has been super lazy lately about actually doing her job. i mean i know x could equal x but do some damn tests to be sure, its not like you have to draw the damn blood or shake the vials manually and read the data yourself...
