Me too. I have low blood pressure normally (and high iron, I just like to be different LOL), and it was worse during pg (the bp not the iron). I had to be very careful about standing up quickly or standing for any period of time. I didn't need any special management though. The worst time was after the epidural when I was in labour with Jack. Epidurals lower bp and even though I was given extra fluid to compensate, I was unable to sit up to push - they raised my head and I instantly felt dizzy and very nauseaous.
