Opk testing

Ashleigh • Married to my best friend. We have a 6 year old son, 1 miscarriage and currently ttc our rainbow baby 🌈👶🏻
I'm currently waiting for AF to show up, I know I didn't conceive this cycle as this was determined via blood work. I started provera the beginning of the week, so I should start any day now. I'll be taking clomid (second cycle) 100mg days 3-7. I'm not exactly sure when I'll ovulate as I've never gotten a positive opk before. My question is when should I start testing? And what times do you ladies usually test? I definitely don't want to miss my surge. I'll be using the wondfo ovulation tests. Is there anything else I should be doing?
