Has anyone used this supplement?

I have fairly regular cycles. I am on letrozole, and apparently it can dry up your CM and I dont produce much in the first place. I have heard that this supplement works wonders but I've also heard that it can throw off a regular cycle. I have 2 bottles of it and I am too nervous to take it. We do use pre-seed also but it has not helped so far.

Anyone have any insight??
