Peak day today, does last night count?

I feel like this is such a dumb question... 
My OPKs have three levels, and I always jump straight to "high" on day 6, I think due to my short cycle. 
So my fertile window in Glow started last Thursday. With Valentines day and all, my hubby and I were going at it all weekend anyway :) Including a late (midnight) session last night. 
​Lo and behold, I got my little egg sign "peak" today on the OPK. So I log this into Glow and my fertile window shifted back too. This all makes sense.
​My (long-winded) question is this: Does last night count? I know sperm lives a little longer than the egg, so maybe our timing was finally just right. As sad as it sounds, we're a little older and we're both tired! LOL. Any opinions on us skipping a day even though today is the highest chance? I've even heard it's better to go every other day with older guys so that they can "refill the tanks!" All thoughts appreciated!
