Clomid/Trigger Cause Late Period?

DJ

So I am basically 19dpo, my period comes 17dpo (have a regular 33/34 day cycle) This cycle I was on Clomid 100mg and Novarel trigger 5000iu on CD15. I tested a few days ago and BFN, so I was wondering if any of you have had your period delayed by clomid and what did your docs say was the cause. My progesterone was checked and showed I likely ovulated. Dont want to keep wasting tests at this point 🙄
