Clear blueovulation advanced test?

Smanatha

Hey guys so I’ve been testing for ovulation with the clear blue and I’ve been getting a flashing smiley face since Saturday but I know once you ovulate you’ll get a solid smiley, has anyone ever used these and got the flashing face for a few days longer? I’ve also been using the strips to test, is it normal that my LH is so high?? I was recently put on metformin and had a cycle this month(I haven’t had one since 2018)
