Confused

First month of ttc cycle was 28 days, next was 29 and last was 30 I've adjusted, and now it shows that we did BD on the last two days of the fertile window. I'm currently at 7dpo. (Period moved 2 days later 9/9) I just started new workout regimen and don't want to mess anything up, when is a good time to test? Or should I wait until af shows or doesnt? Very anxious and have a wedding to attend this Saturday (10dpo)
