Does bleeding and no detection of heart beat in first 5 weeks mean miscarriage?

Not necessarily. Bleeding during the first five weeks of pregnancy can be common and does not always indicate a miscarriage. Many women experience spotting or light bleeding during early pregnancy, which is often related to the implantation of the fertilized egg into the uterine wall. Additionally, at five weeks, the embryo's heart may still be developing, and it might be too early to detect a heartbeat using a standard ultrasound.

If you are experiencing bleeding and are concerned about a potential miscarriage, it is important to consult with your healthcare provider. They can perform an ultrasound and other tests to assess the pregnancy and determine if a miscarriage has occurred. They can also provide support and guidance during this time.
