Am I fertile?!! Plz help😞😢

My cervical mucus is watery on day 15 of my cycle!! What does this mean !!?? According to the app I was supposed to become fertile on feb 6th-14th with ovulation day on feb 13th! Is it normal to have a late ovulation?? Do u guys think it’s time to start trying to make a baby?? In the second picture it stretched a little between my two finger nails
