thanks people for posting. I usually have low blood pressure but this problem didnt start affecting me until i got pregnant and it has progressively gotten worse. It has been worse since i had my thyroid removed but i dont know why that would affect it. I dont have a way to check my blood pressure. and my fev1 is around 70's. so its not like im getting close to transplant stage. I will have to call the dr and see what he thinks.
