Did I miss my peak?

Sam

My predicted date was yesterday but the highest test I got was on CD 12..every test the last few days has been lower than the beginning of the month.

I'm still going to test twice a day to check but it looks like CD 12 was it?? We did BD that morning and the day after so should I just consider this my TWW unless I see a positive OPK? That would mean Sept 6 would be 2 weeks for me
