Do we get heavy bleeding in the first 4-8 weeks of pregnancy?
It is possible to bleed during pregnancy, and surprisingly common, but only light bleeding. Heavy bleeding can occur later on in pregnancy, not due to miscarriage, but problems with the placenta. This usually does not occur until after 16 weeks. If you think you are 4-8 weeks, the only option on heavy bleeding is either a miscarriage or a period. Take a pregnancy test. Even if this is a miscarriage, the pregnancy may still come up positive in a test. My best advice would be to go to a doctor and have them investigate exactly what is going on.
