Ovulation question

I started my ovulation week on the 4th according to my apps the peak day was the 9th. I took tests everyday and the only positive day I got was the 9th. Even if I tested the days after they were negative.

Me and my husband bd everyday from the 4th to the 10th. Would there be chances I got pregnant from the 4th...

I’m just really curious to test ASAP, because my husbands bday is the 25th and I want to announce and plan something if I am pregnant. I bought a pack of 25tests so i could test as much as I wanted 🤫
