Ovulation a week later than I thought

So I dont temp or use opks but I know my cycles pretty well. I have 34-35 day cycle and I always O day 21. How do I know this? I check CM CP and get pretty painful ovulation pain such that walking fast or jogging is a no no. BD is also quite painful but heck for that I dont mind. This cycle...instead of O pains on day 21-23 I got them at day 32. That was a few days to AF . Lots of Bfns and confusion. Then today...7days late for AF I am getting nausea and fatigue. Now if I use my new O of day 32...its around 8-9 dpo. Question is... haa this happened to anyone? Should I be concerned? Should I test coz previous like a million bfns and ghost pregnancy symptoms from the other ttc cycles have left me with anxiety and disappointment...I need uour opinion ladies. What are the chances I pregnt statistically speaking?
