Have you been to a doctor to confirm your pregnancy? A positive HPT can sometimes be false. This sounds like it would be the time for your period.

You should definitely test again, then call your doctor if that test is positive. If you are pregnant, you will continue to get positive pregnancy tests for weeks even after a miscarriage.

Not all bleeding in early pregnancy is miscarriage related. Take another test. Call your doctor. No one on the internet can help you, you need hands on care.
