Help a girlie out…?

What are my chances of getting pregnant? I took an ovulation test on Sunday and it was negative. I ended up taking one on the day it says I ovulate and it was high! My app said I was supposed to ovulated today but once i took the picture of the ovulation test it updated to the 20th. I would be so happy but if I’m not I’d be okay too. Just want to know if my chances are high or nah?
