Three days delayed and got your period doc said you should have pregnancy test resulted was weakly positive is heavy that an early miscarriage or are pregnant?

It is possible that you are pregnant and experiencing an early miscarriage, or chemical pregnancy. A chemical pregnancy occurs when a fertilized egg implants in the uterus, but does not develop into a viable pregnancy. This can cause light bleeding or spotting, which may be mistaken for a period. However, a pregnancy test will still show positive, even if the pregnancy is not viable.

It is also possible that you are still pregnant and the faint positive pregnancy test is due to low levels of the pregnancy hormone, human chorionic gonadotropin (hCG). hCG levels rise rapidly in early pregnancy, but can vary from person to person. A faint positive pregnancy test may indicate that you are pregnant, but the levels of hCG are not yet high enough to be detected clearly.

If you have experienced heavy bleeding or severe pain, it is important to consult with a healthcare professional to rule out any underlying medical conditions.

Overall, it is difficult to determine with certainty whether you are experiencing an early miscarriage or are still pregnant based on the provided information. It is recommended to follow up with your healthcare provider for further evaluation and monitoring to determine the cause of the bleeding and confirm the pregnancy status.
