Ovulation kits....

Cassie

So I started tracking my ovulation through this app and then decided to get the clear blue advanced ovulation predictor kit. I am on my last day of my period and it has the blinking smiley face for high ovulation but I don’t think I’m using it right because I thought I wasn’t supposed to see the high peak until around 10-14 days after my period. I’m confused, has anyone else used these test and if so when did you start it? Did I start to soon?
