I haven't tried this exact one, but have tried a multitude of different hormone balancing vitamins and minerals to no avail in our 3.5 year journey. I have also done yoga, acupuncturist and cupping.
If it is something like a hormone imbalance that is preventing pregnancy then only real relief you will find will be with a good old fashioned Dr, who can prescribe actual hormones to fix the issue. I suggest going to the DR and getting some blood work done to see if it is a hormone issue. For me the money I spent on all the supplements and vitamins and whatnot was all a waste.
However if there really isn't an issue (six months isn't really considered long unless you are over 35, many healthy young couple take a year due to timing and whatnot) than the extra vitamins and minerals will only do your body good until you do get pregnant.
Good luck
