L.C.
I know vitex and soy isoflavones can be a good replacement for clomid - you just don't want to take them with clomid - there are a lot of threads on this over at soulcysters.net (a pcos message board) in the infertility and ttc forum
There's also FertiliTea that has vitex in it and I believe fertility vitamins as well....you could look into those
IDK what the dose would be for vitex if you're taking capsules - but, I would love to know since if clomid doesn't work for me I was considering alternative therapies as well
You should also look into fertility acupuncture
You might want to go to an RE/fertility specialist so they can make sure that you are ovulating and if you are responding then make sure your tubes are open, everything is good and that you are actually releasing an egg...
If you're not I would also recommend charting your BBT (temp) and if you want info on that I recommend fertilityfriend.com
Good luck!
