Can you really tell by doing this?

Has anyone caught a misscarriage past 6 weeks by doing this? I caught my first misscarriage myself at 5w 3 days by continuing to test. I get nervous and need assurance now so I test whenever I feel the need to. Having a heard time waiting for first appt at 9 weeks to see heartbeat. Do you think the tests would show a change at this point if something did happen?
