Presence of any sort of bleeding during pregnancy
is abnormal, except the implantation
bleeding that sometimes occurs and in your case, this is not the time for it. Also, since you are continuing metformin
, you can expect lesser risk of miscarriage
. Perhaps there was a slight bleed and dark brown color indicates old bleeding. Avoid intercourse, lifting weights, take absolute bed rest and consult your obstetrician for advice. If the pregnancy is viable, you may need hormonal supplementation. Take care.
