Ttc. Question on what day I putBD on

Jessica • I am a mother of 3 kids.

If you BD after 12am is that still considered the day before or the next day. For instance the 27 or 28. My chances are higher on the 28th of becoming pregnant but I don’t want to have sex too much. My ovulation date according to here is the 29th and my chances of becoming pregnant on the 28 is 25 percent and on 29 is 32 percent but the 27 was like 12percent. Does this make sense?
