So many vitamins, my head is spinning!

So I bought evening primrose & b6 to help with hormone balance (haven't been tested can only suspect due to crazy PMS & acne during luteal phase). I think I understand the evening primrose -- you stop at ovulation. But what's up with B6? I read both good and bad. I'm nervous to try it and it messes with my cycle this month.  I know my prenatal has some in there & maybe I should just let that be enough? I'm also going to try maca root for the balancing.
