In other words, would there be >an LH surge AFTER the discharge of clear, stringly discharge? The LH surge occurs PRIOR to ovulation -- the peak of the surge occurs 12 hours before teh egg is released. The ovulation predictor kits detect a certain level of LH (a bit before the peak), so they turn positive 24 - 36 hours before ovulation occurs. Changes in cervical mucus also begin prior to ovulation -- ovulatory mucus is very much like egg whites -- clear, copious, sticky. The LH surge is more accurate in predicting ovulation than are symptoms; soem women will experience symptoms despite not having an LH surge high enough to produce an actual ovulation.
