Peak?

Does cycle day 14 look positive? I know I need to BBT but I have horrible sleeping patterns. I did BBT only twice this cycle and on cycle day 14 it was 97.73 but a couple of days before that it was 96.81. I’m just confused because I thought the test line had to be darker then the control like on OPK’s. Also the number is only 0.93. I’m really confused.
