How do menopausal symptoms occur?

I understand that as menopause approaches, menstrual cycles and flow become irregular and menopausal symptoms also occur, but since this varies from person to person, I am not sure if I am actually going through menopause.

My menstrual cycle was accurate, but it kept getting longer and shorter, and I think I also have some hot flashes.

I've heard that some people are really severe...

Some people didn't really feel significant symptoms. Since severe symptoms can cause a lot of trouble, I hope it passes without any issues, but it's probably just a matter of luck. I'm thinking about going to the gynecology clinic to get a hormone test.
