TTC after Mirena

Nickie • Married with children! Missing our twin babies in heaven! NGT👶🏽👶🏽❤️❤️
Hello all my husband and I would love to have a baby. We decided 6 months ago that after the wedding I would remove the Mirena and TTC. My Mirena was removed on 8/25 and my cycle started 8/28 with calculations I should ovulate between 9/8-9/14. Does anyone know which day is your most fertile?  We are TTC a boy and research states the most fertile day with the deepest penetration.
