I had almost all of the menopause symptoms in my early 20s (im 25 now)
And it only occurred to me first now when I looked up menopause. Only symptom I actually didn't have at some point is losing my period, so I'm not sure if it actually was that. I'm also not sure if I had them at the same time or different times. Seems to be gone now
