Hi all! I started using clear blue advanced digital this cycle after ttc for the past 3 months after a miscarriage.

Started testing on day 8, and it was low fertility (a circle)… then for the next 10 days after that I was getting a high fertility sign (blinking smiley). Just when I was getting frustrated on CD21 I got a peak (static smiley) ….. According to the app I was ovulating the 13th, but I didn’t end up ovulating until the 18th. My husband and I were confused based on the app dates and all the high fertility so we did it some days prior… and then once I had a smiley we did it for a few days then. But I’m confused, does that mean I was fertile all 10 of those days before my peak?
