Hi,
Well, there isn't really an answer to that because it seems to work differently with everybody. When I took it I did experience an increase in supply at first but then it leveled off. I believe at least one person on the boards, in the past, experienced a decrease while taking it. I waited until I got ppaf back to start taking it. But remember, taking Vitex doesn't garantee it will make things normal again with your cycles, I've read about some women who actually had delayed ovulation while on it.

I don't know if you saw my other post under the other vitex thread someone recently posted, but I am of the opinion it may not be the best thing for BFng moms to take while TTC. I didn't have such a great experience while on it, I had an early m/c the cycle I took it. I think it works directly against what your body is doing while BFng and forces it get things going when it's not ready. (Again, this is just my experience and personal opinion)

As far as supply issues, it's not just an issue of the vitex lowering your supply but take into account if vitex does kick start your ppaf this early, and you do get pg, the pg could lower your supply bigtime. It just depends how ok you are with taking that chance and supplementing in the coming months if you were to start taking it.

Sorry it's not much help but everyone seems to react differently to herbs and vitamins. Plus, as your probably know since you've had two children, breastfeeding and fertility in general is so different from person to person.

You might want to try posting this question on the BabyCenter TTC while BFng board. They tend to have higher board traffic and you might get a broader range of experience with the herb.

I hope you can get some more advice and good luck with TTC.
