ovulating more than once a month

Erin

please help.. glow can't analyse my cycle as my ovulation doesn't make sense. I usually ovulate around the 6th of every month but last Thursday I took an ov test and it was positive as seen in first two pics. I then took one the following Monday and still positive. I felt like I was ovulating today so took one again and still posotive. pregnancy test is negative and ovulation tests in between have been negative also. I'm so confused...
