Advanced: From empty circle to smiling face! Plus blurry lines in the sticks!

Hi, my cycle is 26-28 days. I used Clearblue digital day 6 and 7 (empty circle) (I had 2 sticks left from my previous cycles). From day 8 I started with Clearblue Advanced a new package and new device. Day 8 and 9 I had empty circles. Day 10 I had a smiling (not flashing) face. Could I have missed the estrogen peak because I started using the Advanced monitor on day 8?
Another question, in comparison to the Clearblue digital where I could see very neat lines in the sticks when I removed them from the device, when I remove the sticks from the Advanced device I see a clear line on the right and a very blurry blue smear on the left of the window that covers another line more or less evident (I have pictures) even on the day of my positive smiling face. How can the reader analyze that mess? Is that normal or there is a problem with my sticks? Thanks
