Need some advice AND HAPPY 4TH OF JULY!!

Okay ladies I need some help , I got my first Opk positive on July 2nd and bd that night and the night before. I decided to take another Opk yesterday because I had some cramping and the test line was waaaay darker than the control line. I’m guessing the cramping could have been ovulation pains But I’m not sure because I’ve never experienced ovulation pains before? But anyways we didn’t bd because my SO didn’t get home from work until late and was extremely tired. I tested again today and it was still positive but not as dark as yesterday. Didn’t bd this morning either because SO had to leave early for work. Did I miss my chance? Do you think if we bd today when he gets home and tomorrow we still have a chance? TTC#2 BABYDUST TO ALL 🤞🏽👶🏽✨

EDIT: I forgot to mention I still have some mild cramping but not as much as yesterday.
