B6 seems to have delayed my period. Can anyone explain the mechanism? I've been putting p5p powder in my foot baths pretty much every day for about 6 weeks or so. I'm not measuring, but it's probably 20-50mg. It's causing breakouts in odd places (behind ears and on neck). I thought it was helping my cycle though because last month my period came on day 29 (had been using the B6 for about 2 weeks at that point), which is good for me because it was starting to be delayed to around day 33. However, this month it's day 35 and still no period. A quick google search shows others have complained of a delayed period when taking B6- some saying B6 is causing a delayed ovulation. The interesting thing is that I thought it was lowering prolactin because my breasts were not as tender this month during pms and I wasn't as irritable. Though maybe I haven't even hit pms yet this month because of the delayed ovulation. Can anyone explain the mechanism at play?
