I'm young and so far at almost 4 weeks on both AA and E,
Literally feeling the same emotionally mentally. The changes are suuuuuuper subtle for me. Like I have to be thinking about them to even notice, and even then it's similar to before, just, different.
It really, truly is a different experience for everyone.
A lot of people say "second Puberty," and in my Puberty I also barely noticed changes. They were suuuuuuper slow and gradual.
I don't know if that's a good baseline for people, but in my experience it's been accurate so far.
