Took Clomid 100mg (days3-7) I am now on CD23

I am so upset right now.... 
I took a progesterone lab test today and got results of 0.3 
I really don't understand why? According to clear blue ovulation test I supposedly ovulated on 8/5! 
Has this happened to anyone else? 
I guess I'm out this month! 😥
