After I have gone 12 months without a period, am I done going through the menopause?

Officially that's you through the menopause - congratulations! 

Just to be aware, though, some women find that they get a random period anytime from a year to 3 years after the last one, but this isn't obligatory - just don't worry if it happens. It's usually just a light bleed or a 'show' and nothing else happens. 

Also, we tend to advise keeping up contraception for 2-3 years after what appears to be the last period (so another 2 years in your situation), just in case.
