Last month I used the normal opk prediction kit by clear blue and got 1 solid smiley face. This morning I'm trying the advanced kit and I literally stopped spotting yesterday from AF and I got a blinking smiley. I've heard that the blinking may continue for more than 2 days. How often should we be having sex during this time of blinking smiley? My glow chat previously had my fertile window starting nov 9 now it's way early. Last month my ovulation was 6 days past what glow said would be my peak date and my period then came 6 days late. Anyone have any experience with the blinking faces?
