Vitamins and Supplements

Anyone else using Vitex, Evening Primrose Oil, and or B6 vitamins?  Also Wondflo ovulation test strips, PreSeed and Conceive Plus.  My cycle alternates between 23-25 days and taking my B6 vitamins have lengthened my cycle and reduced the amount of AF by almost 75%.  Has anyone else had this success with B6 vitamins and is it similar to progesterone?  Trying to lengthen my luteal phase. Also stopped taking Allegra and substituted Flonase as I didn't know all these years that my allergy meds were drying up CM.  has anyone had success with Vitex or Evening Primrose Oil?  Only have taken these a few weeks but the B6 vitamins are working wonders so far.
