What were your first signs of peri?

[Cloud44]

I’ve not long turned 40 and I’m wondering if I’m in the early stages of peri or if I’m too young / over thinking it.
The symptoms seem to come and go: not as much energy as my mid 30s, lacking a bit of motivation, occasional aches, lower libido than five years ago, occasionally forgetting things then I remember.
What were your first signs? Any recommendations of little tweaks I could make / vitamins to research before the symptoms become more regular?

Periods getting closer together.
Then anxiety and insomnia

Apple cider gummies
collagen
magnesium
multivitamins
and gummies for hair and nails

Ah crap I said the G word!
