Help!!!! I need answer

Mrs. • Finally have our babies. R.I.P Kimara Jeffers. Welcome 2 handsome boys Allan and Kayden Jeffers. 👧🏾👼🏾👶🏾👶🏾👦🏾
I'm 42 days cycle. When do I ovulate?? I'm also taking Clomid. 
I'm didn't get my period yet. I should next week after taking Provera. But I'm using this app and its tells me my next ovulation cycle number. Just a head start it says 42 day cycle.
