I've been doing a little research on herbs that promote fertility and found this posted by a woman in a different forum:

I finally decided to do some research and am currently prego. Which is completely amazing to me. I looked into natural herbs. What I found out was that certain extracts help balance my hormones and well now I'm prego. It's the most amazing thing. I took False Unicorn Root, Red Raspberry Leaf, and Nettles. Now after 15yrs of trying I'm prego. It's the craziest thing ever. 1 month with these herbs and presto prego. I don't know if this is what your looking for, but it gave me great relief. Also, helped with the depression as I'm guessing it was all hormones.
anyway hope it helps.

Does anyone else have any experience on this?
