Clear blue ovulation test

Roxanne
Hi guys 
This is my first month ttc so am new to all of this! 
I got the clear blue digital ovulation tester. I tested yesterday on day 8 and got negative (full circle) and then tested today and got peak fertility (static smiley face). 
This would mean I didn't have any "high fertility" days and that I'm ovulating on day 9 
Has anyone else had this experience? Thank you 😀😀😀
