ive not been successful in ttc so might not offer best help but, i am taking 15mg zinc and 400mg folic. i am trying to basic back down what i take supplement wise purely because when i took wellwomen fertility i had anovulatory cycle, spotting before af and sore nipples (never happens) so was very convinced pregnant only to be all "fake". Last cycle i took coq10 and hate late ovulation and spotting. i am trying just zinc and folic now, hopefully new random spotting before af will go as its not happened before.
