Orthostatic Hypotension ?

Victoria
So I fainted yesterday in Walmart and I don't remember any of it I just remember getting hot and sitting down in a chair by the pharmacy next thing I know I'm being woke up surrounded by people asking me if I was okay so I was rushed to the hospital where they run test to find out I had Orthostatic Hypotension which means when I change position my body blood pressure drops causing me to pass out . Ladies this pregnancy has not been easy from suffering from a cyst on my right ovary and a uti where I thought I might lose the baby to finding out I have hyperemesis Gradvidarum to this is driving me crazy. I want a vbac when I go into labor in April so I pray my doctor allows me to go through the process . My last c-section was 6 years ago due to my daughters heart rate dropping when I pushed due to the cord being wrapped around her kneck. My questions is have any of you ladies suffered from hypotension?
