Vaginal bleeding during pregnancy is more
common in women who have previously been pregnant than in women who are
pregnant for the first time.
Very early spotting is sometimes the
result of the fertilized egg implanting in the uterus. Implantation takes place
6 to 10 days after the sperm fertilizes the egg.
Bleeding can be a
sign of miscarriage. Early bleeding during the first 6 weeks or so can be an
early miscarriage called a blighted ovum. Although a
gestational sac has developed, the fertilized egg has not developed into an
embryo. This is usually caused by a chromosomal error in the early stages of
cell formation. On an ultrasound, a blighted ovum is likely to look like an
empty sac attached to the uterine wall.
