How early can you get menopause?

Erika
I'm 31 years old and scared of maybe starting menopause. My mother lost her period at age 34. I get my period every month for about 3-4 days. The second day always the worst, heavy and lots of cramping. I have a 10 year old but would want another baby, not  anytime soon. Does anyone know the symptoms of early menopause?
