Pregnitude

Caitlin
So I'm thinking of starting pregnitude. 
I've taking progesterone to induce a period and then took clomid and it didn't work. Before I start clomid again I want to try this. 
But I want to get feed back from those who have taken it before. 
Should I get another prescription for progesterone and then take it or will it help induce a period? 
Any cons to taking it? 
How quickly did it work for you if it did? 
Why or why not would you recommend it? 
Any other fertility aid suggestions are more than welcomed!
