First round Clomid fail - Question for round 2

Aubrey • DS born May 21, 2018, surprise with #2 due Aug 2019

My first round of Clomid was a fail. I ovulated, but no pregnancy. Now to start the next round. Today is CD3 and I will start again. But my question is, I ovulated on CD12 last time we started BD on CD8. Should we start to BD sooner or stick with CD8?
