A school friend of mine went through the menopause aged just 19, the doctors told her "have a baby now because this is your only chance" so she did,
And another school friend of mines little sister started puberty aged 2/3
That's a sad thought, going into menopause so young.

I would have tried to have a baby first too; did your friend manage to have a child (if you don't mind me asking)?
My mom had a hysterectomy in her early 30's due to PCOS; she always says she probably would have had another child if she could. Early menopause was difficult for her, I can't imagine it happening even younger.
