How many days before your missed period can you use a pregnancy test?

Several. You ovulate 2 weeks before your period, and the pregnancy tests can detect small amounts of b-hcg (once your egg is fertilized) in only a few days. So, theoretically, you may be able to check a test several days before your "missed period.".
