Got a opk lh surge yesterday and then last night I had pain on the right side which I assume was ovulation pain since it didn’t last longer than a couple of minutes and felt like cramps. However today is still showing the opk as having a lh surge.

Has anyone else experienced this? I am not sure what would be better to have ovulated last night/today or to possibly ovulate tomorrow. The reason I am wondering is because my Husband works 48hr shifts and he just went on shift this morning. I am worried about possibly missing my ovulation day.
