Welcome and thanks for the query
The symptoms mentioned by you are suggestive of anemia since you stopped the iron tablets long back.Extreme fatigue , ringing in ear and restless leg syndrome
are suggestive of Vit B12 deficiency and low calcium intake.As you are having full term breech , the symptoms of pressure on diaphragm may increase the respiratory distress
or shortness of breath
.If it is your first pregnancy with breech confirmed then C section is the only answer.Your obstetrician will repeat the Haemoglobin
and other investigations and start the treatment accordingly.Pancreas test is done in case of elevated blood sugar levels or excessive weight gain
of the mother as well as the fetus.As you are approaching the due date your problems will be resolved very soon so do not worry and leave yourself in the hands of your obstetrician.
Best wishes and good luck.
