Chinese Herbalist - success rates???

Hi just wondered if anyone has decided to go all natural and try traditional Chinese therapies? I have been TTC for nearly 4 years and been on clomid etc with no luck. I have had my tubes checked and flushed with the blue dye and everything was fine there. I decided why not give it a go! So I was told some things about my fertility from my Chinese herbalist which was very interesting. I had to brew up herbs for 2 weeks - this was the most foul thing you will ever taste!!! Anyway I am now on the capsule form called Pro-creation R and have a months supply. When I was on the herbs my cycle was a 28 day one which is great for me. I did have a lot of cramping and I mean I was in so much pain I was sweating then fainted!! I am currently on day 22. Would just really like to know anyone's experiences on this :)
