Trying for baby #2

So my estimated ovulation date is Saturday the 3rd with my period track app I use. Usually always accurate and my ovulation tests are getting darker & darker so it would make sense I would ovulate then. I know I’m in my fertile week. My fiancé & I BD the 29 & today(31st) if we don’t get a chance to the 2nd or 3rd what are my chances of still getting pregnant?
