I need help girls

G

Hey girls. My cycles are normally 29-30 days. Always regular. Ovulation happens around cd17. Can someone help me please. It’s cd23 and I finally got a high on my opk. But one was at 4:42 pm and I just took one around 8:59pm. Please have a look. Is my surge only 4 hours? We just BD after my 8:59pm test. Nothing unusual to cause such a delay in my ovulation this time around.
