How can I tell the difference between implantation bleeding and a miscarriage?
Typically bleeding associated with a miscarriage is fairly heavy. Bleeding that is as heavy as or heavier than a normal menstrual period is probably not related to implantation. Again timing is important. If the pregnancy is advanced beyond the 5th or 6th week, bleeding much more likely represents a threatened miscarriage. Clotting, cramping, or multiple episodes of bleeding are very unlikely to be implantation bleeding.
