I am 43 years old and for as long as I can remember my period has come between 23-26 days. Last month it was late for my norm at 31 days. Flow and length were normal. As of this cycle I have not gotten it yet and today is day 30. I am not pregnant. I changed jobs 2 months ago and routines. I have health anxiety and always think something is wrong. Can you shed some light on this for me please? - Lori
