Thanks for the good info... I am wondering if you have any idea on my particular situation: I have a very short luteal phase... sometimes only 5 days from Ov... and then in addition a strange period, it comes for 2 or 3 days, goes away.... (nicolejardim.com)
While the luteal phase usually lasts between 12 to 16 days, a short luteal phase (one that lasts less than 10 days) negatively impacts fertility. (ohbabynutrition.com)
Studies have shown that women with low melatonin and serotonin levels have a shorter luteal phase (time between ovulation and menstruation) and consequently have a lower chance of conceiving. (wellnessmama.com)
