OPK Clearblue

I started using the Clearblue advanced ovulation kit this month. I had 2 days of circles, meaning low fertility and I am on 8 days of flashing smileys, meaning high fertility. Has anyone ever had 8 days of this? It seems to be an awful lot and am wondering if I’ll get the solid smiley (peak fertility) at all? On the 7th day of the flashing smiley I did have light spotting. I have exactly a week today until my period is due and I’m always 28 days. Anyone been through this??
