Ovulation dates confusion

So on the eve app my ovulation dates are October 31st to November 6th. BUT on the glow app my ovulation dates are October 29th til November 4th. My boyfriend and I had sex October 24th, 25,27,29. Which ovulation dates are more accurate? I was trying to have him do it inside me two/one days prior to ovulation but now since the dates are different, idk. Do you guys think this will work with the days we already did it? I’m having white milky discharge today and cross.
