When to start testing?

I am on my first month using Clomid.

I took 50mg clomid cycle days 3-7 and currently on cycle day #10. When should I start my ovulation kit? And once I hit my peak how many DPO did your doctor tell you to start testing for pregnancy?

Also, i will be using Progesterone suppositories 4 days after I hit my “peak”. Does anyone have any experience with this?

Thanks in advance xx❤️
