I would mark on the calender when you felt it and watch, if AF comes in 2 weeks from date on calender, then probably pretty good chance you O'd. I realize that does not help you now, but you may discover a pattern. I know DW can almost always feel her egg release. If she tells me she felt a pain in that area and I look it up in the software program we use, she is usually spot on for the date ovulation is predicted.
