Tonight I was sitting here, watching a movie with my husband when all of a sudden I got really dizzy... like my head was spinning. With my last 3 pregnancies it happened when I was dehydrated or needed to eat... or if I got up too fast. I know its not that I'm dehydrated because I have a glass of water in my hand, I also know that its not that I'm hungry because I'm stuffed... and, like I said, I'm sitting... But, yet, I'm dizzy... anyone else have this? what caused it? What did you find that helped?
