You should have intercourse on the day prior to or on ovulation, that increases your chances.
First Congrats on the Marriage....Also wanttobeamumagain is right....you have to start calculating your ovulation days so when you are fertile the egg will be waiting on the sperm.....Sperm normally lives about 3 days to about 5 days and egg only lives 24hrs which gives no window for error...Ive been trying for about 4yrs but only this year have I really been timing and calculating....so good luck!
You need to have sperm waiting for the egg, so you need to have sex before ovulation. Sperm can live for a few days inside of you.
