Do I have a good chance this month?

Nesa β€’ Mommy to a 15 yr old boy, a 2 yr old boy, and 1 angel baby girl lost at 4 days old to HLHS. Healing from a huge loss...🌈🌈🌈 Due 8/24/19❀️❀️❀️
Used preseed this time. Do you think I got enough BD in to stand a chance?!? Anyone get a BFP and didn't get too many days in on their fertile week? TIA πŸ™πŸ½πŸ™πŸ½πŸ™πŸ½
