It is true that placental perfusion may be low in smoking
mothers. Yet, it is too early at your stage of pregnancy
to say for sure. This can be detected well at your next sonogram. As per the low amniotic fluid
levels, you should take as much bed rest
as possible preferably in the left lateral position ( this is going to increase blood flow to the baby), take plenty of fluids, eat a healthy diet and continue with the supplements. Amnio-transfusion is the last resort of treatment used in severe cases with its own risk implications. In course of time, with these measures, your condition is going to improve, so do not take stress
and quit smoking. Wish you good health.
