Anyone have any success stories with conceiving only being able to BD 1 day in their fertile window? More specifically- further away from O day?

We were only able to BD 4 days before ovulation. I didn’t have or notice fertile CM this month, so I’m assuming my chances are not good :(

I got my BFP on CD 12 so ovulated CD 13.

Officially in the TWW. Would love to hear some success stories❤️

What does everyone think? Am I out?? Is there a good chance? This is my first month TTC after an early miscarriage
