Help 🙁 Could I have missed it???

Jennifer

I've been tracking my ovulation and I have always ovulated on day 14/15. Is it possible that my surge was so short between days 14 and 15 that I missed getting a positive opk test? (It was darkest on CD14 pm.) Or should I keep testing? I have never missed a period, and I am always very regular. I'm just confused on when to BD. I included pics from this cycles' tests as well as last month's for reference. TIA!
