My period finished Monday. I took my first opk Tuesday and as expected it was a solid empty circle. I took another today which was only day 9 of my cycle and it showed as a static smiley. I'm confused as I usually would get at least 2 to 3 days of flashing before solid smiley and it would usual be around day 12 to 14. Has this happened anyone that could help? Day 8 just seems so early for me. Last month I did n have any flashing smiley it went from empty circle to solid but over a few days not immediately next day and not as early as this.
