Insulin help

So I do insulin before each meal and at night before bed. Normally, I take my bedtime one at 9:45 but I got super busy today. So I didn't eat my dinner until about 9:20 and took my meal time insulin when I ate. Should I still do my bedtime insulin? Maybe at like 11 to space them out better? I didn't even notice what time it was before doing my insulin when I ate.
