Am I going through pre-menopause @ 27?

I am for some reason nervous that I am ?? my periods are on average every 24 days, they might be a little shorter now but I have been told my my doc that I am probably getting ovarian cyst b.c of pain and fluid around my ovaries. I also have have major digestive issues for the past 8 months I do get night sweats but I am not sure if its b.c its hot in my room also my mom is going through menopause @ 55. Does this sound like pre-menopause to anyone, or do I sound like a candidate?
