So confusing!

Ashley
So Friday Aug 7th I took a clear blue digital ovulation test which came back as peak, took a Walmart brand test Saturday Aug 8th which also came back positive. dh and I bd'd all weekend and just because I'm and obsessive tester I took another CBO test Monday Aug 10th that came back at peak and took another one today Aug 13 that was peak. What am I doing wrong?!
