Inositol!?

I've been taking inositol in powder form for about three weeks! I have PCOS and I usually have my period every four and half months. My doctor prescribed Femara (letrozole)  for six months to help me conceive, which I did not! After the six months my irregular periods returned so I decided to try inositol and yesterday  I started my period! yay! I believe that inositol is the reason behind af showing up! So I'm just curious if anyone else has tried inositol and if they conceived while taking it!?
