Help please

I’m new to ttc so can anyone offer some insight?? We had sex on the 25th, 26th and 28th. I’m just curious if this app was accurate for you guys when tracking ovulation. We decided if we don’t get lucky this month we will actually track it next month. My SO left town for work so we won’t be able to have sex until next week.. could this possibly be enough sex to conceive ??
