Ovulation miscalculation?


Ok so sometimes i can feel when i ovulate & 97% of the time it's the day the app predicts but not this last time.

Fiance and i bd the whole week of ovulation since we finally had no roommates at the house 😂

Well a week after the prediction day i felt the pain and now I'm 2 days late with none of my normal af symptoms.

Has anyone else had that experience?
