OVULATION TESTING

Jossie

so the past 3 days of ovulation testing I have been getting my blinking smiley faces. So I’ve been testing once in the morning and once before I go to bed to be able to catch my solid smiley for my peak ovulation. So this morning I got a blinking smiley face . I just now tested before bed and had a solid BLANK circle meaning I did/didn’t ovulate ? Like is this normal or happened to anyone else? Should I test again tomorrow morning ?
