Inositol / pregnitude

Anna
Since getting off BC, I haven't been regular with my periods.  I have done weight loss and had one period, but then I experienced sporting the month after and not a full period again.
I've done research and found that many woman have taken Pregnitude and have ovulated very quickly after taking it!  Have any of you tried it?
Researching more, pregnitude is just folic acid and inositol.  I'm taking prenatals which have folic acid, so I ordered inositol because it was much cheaper than pregnitude.  The reviews also had numerous woman with success stories.
Have any of you used either?!?!
