Have any of you taken B12 to lengthen your luteal phase? Mine is usually 11 days but last month it was 9 and this month 10! I did take progesterone cream last month that I think messed up last month, but I'd rather have a 12 day LP anyway. So how exactly do you do it? I got a B12 complex with 100mcg B12. Do I take it the whole cycle?
