When you would you test for pregnancy

Adjoa • Baby Girl 1.28.17🌈. Baby #2 due 9/27/2021.

I took clomid from June 19 to June 23. I did not use opk this cycle just baby danced like my OB stated. I am not sure how many dpo I am or anything. I am so confused. This is my first round of clomid 50 mg after taking a break 3 years ago. I took a test yesterday it was negative but I am following this calendar. TIA
