Preseed Question

First time using preseed- I just got a smiley on ovulation test. I used preseed as soon as I got a positive. My husband leaves for work super early (3 am) and doesn’t get home until about 6 pm. Should I use preseed and BD again in the morning? Or wait until tomorrow evening? Also, do you continue using preseed day of, day after, and day after that?? Thanks ladies!!
