Hi Ladies, I'm monitoring myself mostly by OPK (the sticks, not digital), and based on this it seems my luteal phase is mostly between 11-12 days. My menstrual cycle is usually fairly regular (27-29 days), but I have occasional ones that are shorter (e.g., 24-25 days). Have you found that your LP remains mostly the same, regardless of menstrual cycle length, or would it proportionately adjust if your cycle is shorter?
