Thought I already O’d

I thought I ovulated on the 24th putting me at 4dpo. I decided to take another opk tonight and it is extremely positive. I’m pretty disappointed because I won’t get to bd until tomorrow. I know I still have a chance but I was hoping to try a little harder this month. Anyone else around the same cycle day?
