TTC from 3 months ! don't wanna c my AF on 2nd Feb!!

Anu
Yesterday was CD17 tested with clear blue advanced digital ovulation kit for the first time n got a clear Smile,think it's Peak also my BBT dipped n we did BD.
Today it's CD18 n when I tested it was Just 'O' on screen n my BBT raised n still BD'd.
I didn't realize my peak days r so early as normally don't n do u guys think I'm going to get my BFP this time? I just don't wanna see my AF :(
