Your wife is 35weeks pregnant & delivery can occur within next 5weeks.
But,if, platelet count
is very low means less than 50,000,
she may go in intrapartum or postpartum haemorrhage,
means,risk of bleeding is much more during delivery.
so,consult your gynaecologist,hospitalise your wife &
arrange for platelet transfusion to improve platelet level.
In this case,harm to foetus is less,but, maternal morbidity or mortality
is much more.
