so confused 🤷🏻‍♀️

So my fertile window was supposed to start on Friday. I decided to get myself the clear blue digital ovulation test this month and try it out. I started yesterday and as expected got an empty circle! Today I got a flashing smiley and glow has changed my whole prediction to say my fertile window started on Tuesday 😩 we BDed yesterday but I don't know what to do! I also took a cheapy amazon and that's just showing the faintest line. Has anyone else used these digitals? What do I do?
