As your symptoms present, it looks like you had a bout of bleeding from your low-lying placenta. If the bleeding has subsided now, and the sonogram and clinical examination have ruled out any hazards to the baby, then you should remain in observation, preferably in a well equipped hospital. You should take absolute bed rest
, avoid intercourse and stress
. You may need a blood transfusion
if the bleeding is severe. Your thyroid
is of not much problem if care is properly taken during delivery and if you continue taking the drug to keep your thyroid hormone levels in the normal range. You will be delivered by a caesarean section
as soon as the baby is mature enough, at around 36 weeks. If only the bleeding remains uncontrolled, you will have to be delivered now and it is going to be a preterm delivery and the baby should immediately be put in preterm care. Please take further instructions from your doctor. Wish you a safe delivery.
