is true that if you had an early menustration you will have early menopause?

It seems to have little to do with it - in fact some women are early start, late stop I was at the 'later end' of start up being almost 14 when most of my friends had been hit between 11 and 12. Now - I started into menopause about 42 when the average age to Start that is closer to 50 and I have one friend who will be 50 this year and she hasn't had the First Symptom of menopause yet and she started around 11. I think it may have shifted over the years due to changes in lifestyle, nutrition, food groups, medical care and all that.
