Hi all
I saw a naturopath today (my local chemist employs one) and she said if you are TTC (esp. on IVF) it's best to stay away from most herbs but especially chaste tree/vitex. Apparently it increases progesterone production but you cant take it when you are pregnant. Problem is, if you stop it when you are pregnant, especially suddenly, it can cause miscarriage.

I have done no other research on this but I left the chemist without it!!

hope this helps!
