I got a second blinky face OPK for the month... My last one was 8/3, had a solid 8/4 and thought I O'd 8/5. Thought I was having implantation early this AM - I took an ovulation test for the heck of it and got a blinking smiley again.. We had sex around 5a.. I can distinguish SOME of what's left over cum, but I got this too and wondering if it's ewcm and I'm actually going to O now?!
