Hi all just wondering if anyone has tried taking vitamin b6 to lengthen their luteal phase? Mine was 10 days last month spotting from day 9. Does anyone know if it makes you ovulate earlier or makes AF come later? The only reason I ask is that I am cd7 and I'm starting to get a line on my OPK not a positive one but its there.. I don't normally o until cd15/16! I've only been taking b6 for 8 days..
