Clear blue digital OPK

Dorothy

Hey everyone, so this is my first time really tracking my ovulation. I bought the Clear Blue Advanced OPK digital kit. I started testing right when my period ended- to see what’s going on with my ovulation time. I started testing Tuesday, I got a blank circle, and then beginning Wednesday I’ve had a flashing smiley face- but no solid yet. Everyday I test twice now, once in the morning when I wake up, and the next between 3 and 4 pm. Is it normal to get a flashing smiley face for a week? I’m starting to feel like this test is wrong, and maybe I’ve missed my ovulation :(
