Pregnancy test: Many home pregnancy tests claim to be accurate as early as the first day of a missed period but accuracy varies. If important to confirm pregnancy depending on how far along you could be, a doctor can get a more accurate blood test or perform an ultrasound. Always use protected sex if you do not want to get pregnant or contract an STD.
