HELP!! CD 41 No Period.

I have never experienced this before. My husband and I really didn’t have sex last month (maybe 3 times) he always wears a condom and pulls out before. I’m truly not worried about pregnancy. I took two tests yesterday and both came back VERY negative. I do use an oura ring and track ovulation- and I had some ovulation test strips laying around. I’ve had a lot of discharge the past week and decided to just do one. The result came back VERY positive for LH. Why am I ovulating on cycle day 40?! I am so confused and feel crazy.

I recently started a new diet and personal training program around 3 weeks ago. To me it hasn’t felt super intense. Just more walking and 2 strength training days per week. No sugar or gluten. This is the only thing that I could think would be impacting my cycle. Please someone help me feel not crazy. 😭
