When did I ovulate?

Hali

Today for me is CD 14. The first day of my last period was April 27th. I got this smiley face with the CB digital Ovulation Test on the May 7th (CD11) at 10:30 p.m. Then the next morning (may 8th) I took another with FMU and got another smiley that morning (CD12) and another smiley that night before 10 p.m. the smiley was gone by time I woke up May 9th (CD13). So does the smiley face mean I ovulated?

This is what the smiley face looks like. This is the one that does not have the smiley face that flashes. The Advanced ones is the ones that flash and are purple. This is not the Advanced! Would appreciate any advice on what to use and how to track my ovulation.
