4 days of flashing smiley face

I have been testing every morning since day 15 of my cycle I had O day 15-17 then day 18-21 I’ve had flashing smiley faces is this normal? I don’t normally have more than 2 flashing smiley faces than one solid smiley face. I am hoping tomorrow will be a solid smiley face but I’m not too sure what’s happening. Also curious If because I have taken Clomid this last cycle does that cause me to have more flashing smiley faces?
