clear blue digital

Im on my second round of clomid 100mg w/ 100mg metformin. This is my first time ever using the clear blue digital advance opk. So ladies how many days of the high peak flashing smile faces did you get before a solid smiley face? I'm on day 3 of a blinking face and getting nervous I might not ovulate 😕. Trying really hard not to get my hopes up and just let it happen.
