In the current scenario, this spotting cannot be taken lightly in view of the past history of miscarriages. You should report the matter to your consultant immediately, get a pelvic/trans-vaginal sonogram to see the location of the gestation sac and the viability, take absolute bed rest
and avoid all forms of stress including intercourse. If the cause of your previous abortions has been understood, specific treatment needs to be applied as a precaution. Please try to avoid anxiety
as this is not good for the pregnancy
. The spotting could be from the inflamed cervix
and not from the uterus
at all. Hope your query has been answered. Wish you good health.
