Hello,
I started taking Agnus Castus recently, as I have been off the contrceptive pill for eleven months and was still struggling to produce my own progesterone.
They say it takes up to three months to take effect, but I got it to work within two weeks.
I have explained how in the discussion 'Good news for anyone who has been on the pill and is now struggling' on mumsnet.
I hope this can help other people too
Good luck!
