A home pregnancy test is accurate if the reading is "below 5". The extended time before your period may be due to delayed ovulation, which post-pones the onset of the next menstrual event. This can happen with increase stress (emotional, school, work, etc.). See your GYN physician if this continues, for additional testing (ultrasound).
