You have to go 12months without a period to be menopausal I believe. Given my last period was in Septemebr 2016 I was thinking next month I'd be sent my official membership card but today I'm having a period! Has anyone else had such a big gap? Does the clock start again now or do I have to have a number of periods before the one year timer resets to zero? I was secretly pleased before this as apart from aches and pains in my lower back and knees (which make me feel older than 49 (50 in Jan)), I was getting away without some of the more difficult symptons of the process such as hot flushes. Now I'm not sure I have even been in the process
