Depending on the dog's size it can be anywhere from 6 - 24 months before she enters her first heat cycle, though from what I've seen and read 8-9 months is pretty typical.
It doesn't mean she's an adult, no. If your 6 month JRT goes into heat, for example, she's still a 6 month puppy.
Just like with humans. If a 14 year old starts her menses she's not suddenly an adult.

Actually, dogs don't have menstrual cycles. They have estrus. It's similar to menstrual in that there's bleeding, but works differently. They can get pregnant during estrus.

A dog is considered an adult at the age of 1 year, but they can get estrus (commonly known as the "heat cycle" anywhere from the age of 6 months to 2 years.
