well i take siberian ginseng and vitex (both are in fertil-aid)! i havent conceived yet though still trying!! you just kinda have to figure out what situation you are in and what herbs work for that. I have Vitex cus my O is not very often and i take the ginseng because i have a huge problem with being cold all the time and they say u wont get prego if u cant maintain your body temp. properly! I did my own research online and from taking my temps i figured all this out!! My friend did take the fertil-aid and is now prego but i think she was not taking it the month she got pregnant just clomid. i ll ask and tell her to come post for you.
