Does 12am still count as my most fertile day?

Klisha
Dec. 1st is my most fertile day and my husband and I had sex at midnight. Does that count as my 20% day(December 2nd) or does it still count as my 30% day, or is it in between?? 25%??? Lmbo! May the Lord help me, LOL. I never know what day to put that under.
