There is no specific cause that can be attributed to this intra-uterine bleeding during pregnancy
. It is not necessary that it should repeat itself; in majority of cases there is only a single episode of bleeding and the clot subsides in course of time and pregnancy progresses normally. Small clots do not harm the fetus; it is only when the clot interferes with the circulation in the placenta that a miscarriage
can occur. The precautions to be taken in the present situation are absolute bed rest
until all symptoms subside, avoidance of stress
and intercourse. Ask her to take plenty of fluids, fresh vegetables and fruits. Take care.
