When is the soonest I can test with my new cycle after mc?

Okay I know....this question again?! Test on expected AF! The problem is, I don’t know when that is! My cycles were always 30-32 days with ovulation around cd 17. I had a miscarriage in January. Since then, my cycles have been 29 days EXACLY (2cycles so far). Ovulation has been cd18. Last cycle I planned on testing cd32 when AF arrives earlier than expected (11dpo). Soooo my question now is.....When is the soonest I can test?? Or better question, when is expected AF since my luteal phase has been shorter than usual lately?? Cd29 (4/6)?? Or Cd32 (4/9)??

What would you do??
