Hi ladies! I am ttc and have decided to try Agnus Castus for the first time this cycle, bc I've read so many good things about it. I got a pack from Holland & Barrett. To my surprise it says on the box that each tablet contains 4mg of the herb and is to be taken once daily. While I've been reading that other ladies are taking 500mg or even 1000mg daily. I don't understand! What dose should I be taking? Is this 4mg going to have any effect at all? It also says on the box that you shouldn't take this if you are pregnant or trying to conceive. I'm really confused! Can anyone help me out here? Doctor hadn't even heard of it and said we don't recommend herbal. Thanks in advance.
