Ovulation

I had bought the advanced clearblue ovulation sticks and a week after my period I had gotten high fertility the flashing smiley face. The holder had broken so I had to buy a new one. I have been testing ever since and just today I had gotten another high fertility. Could it be that I might ovulate that late in my cycle? I’m on CD23. I do have irregular periods. I’m nervous that I may not ovulate at all. TTC#2
