Chance of pregnancy?

I didn’t track ovulation this month consistently. The day the app said I was ovulating I took a test and it was positive. We baby danced the week before ovulation, the day I was ovulating and then a week later. I took a test Friday (3 days ago) and it was negative. AF is supposed to come tomorrow, is there a chance I could still be pregnant?? ...month 5 of TTC....
