help! why is my ovulation test saying another fertile window?

so i had peak fertility on my clearblue ovulation kit on the 8th of february and then i tested 48 hours after and it was negative so i assumed that was my ovulation and i had cramps etc, anyway i tested today out of curiosity as i've come off the pill last month and it's saying "high" fertility again, not peak tho? does anyone know why? i'm all new to this!

TIA x
