Can someone anyone PLEASE help me understand what’s going on with my body and ovulation this cycle?

Hi all, I am feeling so defeated and sad. My husband and I are going on month 5 of trying which I know isn't a long time. We have had a hard time with timing this all properly but I was super excited that this month we consistently BD during my fertile window. Jokes on me, I never ovulated and still haven't. I got a positive LH test on CD 12 and we BD on CD 11-13 now it's CD 18 and my temperature has not spiked to confirm ovulation. Why? I feel like there is something wrong with me. What do I do? Has anyone had something similar happen? Do I keep taking LH tests and tracking BBT in hopes my body will try again? Do I keep BD until then? I just want to cry
