Ovulation - clear blue

I have been tracking ovulation with the little green strips and having no luck at all for months, this month I’m using the clear blue connected test and had a few days of low just a circle. This morning I got a flashing smiley for the first time, and 3 hours later still flashing smiley - but I took a strip with the last one, it’s no wonder I wasn’t getting anywhere with the strips if this is how it looks?!  Anyone else had this 
also would be interested to know how many days of flashing smiley people had.
