Last menstrual period not matching up to due date
I just realized that my due date and my last menstrual period don't match. No, LMP isn't accurate for many people. It assumes an ovulation date of day 14, but many people ovulate later. The most accurate date would be ovulation date, but many people do not track that accurately cervical fluid, cervical position, basal body temperature.
