Opk help!!!!! Since no one is answering.

C

We are trying for #2 and my ovulation dates are different from the first time.

On these opks I have gotten 3 positives in a row. (Circled)Each day darker. Today VERY dark

Do I go off of the first positive opk or the darkest?? We have baby danced every other then the last 2 nights in a row.
