Hello! I read carefully your query and understand your concern. It s not uncommon to have a drop in blood pressure during pregnancy. Pregnancy can have an effect on blood pressure. It occurs because the circulation expands during pregnancy and hormonal changes cause the blood vessels to dilate, leading to a lowering of blood pressure. The blood pressure begins to fall in early pregnancy and is usually at its lowest sometime in the middle of the second trimester. These lowered pressures usually last during the pregnancy and return to original levels afterward. The symptoms you are having like blurry vision,dizziness are symptoms of low blood pressure. You can take some steps to minimize the symptoms and promote safety, such as the following: -Sitting or lying down if they feel faint, to avoid falls. -Avoid standing up too fast from a seated or lying position. -Lying on the left side, to increase blood flow to the heart. I suggest to consult this with your doctor and if the symptoms of low blood pressure get worse please seek medical attention. Hope my answer has helped. Take care. Dr.Rovena
