When did you BD the cycle you were

Doing <a href="https://glowing.com/glow-fertility-program">IUI</a>? I have my CD12 ultrasound this Friday. If all goes well, trigger shot on Saturday. Then <a href="https://glowing.com/glow-fertility-program">IUI</a> on Monday. When should we BD? Should we BD before CD12? I just don’t want to hurt my chances. I’m so confused how this is seriously down to such a science. Can I BD CD11? I was thinking every other day before the ultrasound, then see what the doctor says after that. Thoughts? Advice? Tips? Any and all is greatly appreciated!!
