placenta not supplying enough oxygen causing low fetal weight.. at second trimester.. I am very much upset. What to do

A. That’s not a healthy sign but sometimes what happens is due to thickness in the blood or maybe there maybe a little bit of clot in between which is flowing it down you can check with your doctor on that and they can advise you with some medicine or supplement that is going to help in thinking of blood and easy passing of oxygen and blood
