Opinions Needed

I got off birth control the end of July, and I downloaded this app to help me track my fertility. On my BC, my period came every 28 days, my first month off it came at 32 days, and this month at 30 days, so I’d say my body was somewhat regulated. We have been having sex on the days that the app suggested and of course on other days that we just wanted too. We had sex this month the day before ovulation, the day of, and the day after. Should I be worried if we don’t get pregnant after this?
