About this symptom
Spotting
Implantation bleeding or spotting is a normal pregnancy symptom and may occur from 6-12 days after conception. Many women do not experience this symptom at all. Each woman who does will experience it very differently - Some will spot lightly for a couple of hours, while others may have some light spotting for a few days. If the bleeding occurs after the expected period, it is usually not attributed to implantation. Studies show that anywhere from 20-30% of women experience some degree of bleeding in early pregnancy. Approximately half of pregnant women who bleed will go on to have a normal, healthy pregnancy. Be sure to contact your physician if you experience heavy bleeding or bleeding accompanied by painful cramping, or if you feel the bleeding is not "normal".
