Though you should never put pressure on yourself to get pregnant that fast, you may have your reasons. One helpful tool you can try is the ovulation kit. You can get these in stores near the pregnancy tests, or you can find them online. These are something you use for a week around the time you think you may be ovulating. When they indicate that ovulation is about to occur, you can time your intercourse accordingly. For best results when trying to get pregnant quickly, try having sex each day for three days before and one day after ovulation.
