Ovulation Testing

Hello! This is my first time posting! I need help. I have been taking clear blue digital ovulation tests since day 10 of my cycle. On day 12 I got the blinking smiley face! Yahoo!! Except, I'm still getting that everyday and now we're at day 19 of my cycle. My periods are pretty irregular, so I'm hoping ovulation is on its way, but has anyone else experienced this?? I just want that solid smiley face! 😖
