ok has anyone tried both and which is best im new to this whole thing
You will find a LOT of people with bad things to say about agnus castus, with the odd positive experience thrown in.
As for Soy - if you know you are ovulating well on a regular basis, you might not really need to take soy.
There is a lot of info out there, sometimes it will seem like too much, but you really need to do quite a bit of wide-reading on the subject and make a decision based on what you think is right for you.
I take soy, as my GP told me my body has to work hard to ovulate (this was after getting CD3 and 7DPO bloods done), and after reading things on here and many other websites, decided it was the right thing for me to take. Previously I had considered AC, but my research made me never want to go near it.
It is very tempting to try everything all at once, as once you want a baby, it can become a bit all-consuming, but you need to listen/observe your body, and work out what is amiss (if anything). If it ain't broke - don't fix it!!
How long have you been TTC & how old are you? Have you spoken to your GP - mine was full of good advice.
EDIT: Just read a bit of your journal, did you have any issues when you were TTC#1, what birth control have you been using up until now?
