Hello doctor I had last thyroid test in January 2022 And it was 10. Something and doctor prescribed my thyroxine 50 mcg tablets and then my periods were coming on time but in Sept 2022 I was very much stressed out due to some personal reasons and I was taking my medications on time too but I didn't get my periods in Sept 2022 and still there are no symptoms of pms too And I'm not at all sexually active so please tell me what should i do ?could stress be the cause of delayed periods as I was very very very much disturbed in Sept 2022 .
