Did I miss our fertile window?

Maddie
I have been on my first Fertomid cycle.
​Normally have 27/28 day cycle with ovulation on CD14.
​This time did first OPK test CD11 and gave definate +;thus indicating ovulation on CD12-is this correct?didnt chart bbt.
unfortunately husband was away so upon his return we BD on CD13.
​Did I perhaps ovulate earlier due to fertomid  and missed our fertile window?
