Irregular Periods & mid cycle bleeding opk

sharon

I recently got the clear blue ovulation test kit & the first two days I got a empty circle, then the next two days I got the high fertility flashing smiley face..... When ovulation occurs the smiley face is supposed to not flash. Well with it saying I'm im high fertility I'm still spotting blood??? Is the ovulation test wrong? Or is it possible to bleed during it? Sorry just so confused 🙄🤷🤷🤦
