Brewer's yeast and trying to conceive?

I have been taking 2 pills a day of Brewer's Yeast.I have acne and it is helping a bit to clear it up. IN addition to benefiting from the B complex vitamens in it. But a minor setback of taking Brewer's Yeast is an increase in l discharge (the one u see all month). Would this discharge stand in the way of conceiving a baby? I am tracking my ovulation through OPK, because the cervical mucus is misleading. I have clear jello like discharge when I wipe (sorry for the detail). Today is the thirteenth day of my period, according to OPK I still haven't ovulated. Anyone have tried brewer's? Any advice? Thanks a lot
