That was me with my 3rd, it was awful. It would get so bad sometimes, I would feel like I was going to pass out. The doctor told me that I was eating too many carbs and not enough protein. So all I would eat was protein. Still it was happening to me. Blood tests were fine, there wasn't anything the doctors could tell me. My mom said that the same thing happened to her with her third. The baby stays too far back, and is constantly resting on your important veins in your back. I think that was why it happened to me, because I would lay on my back, when I wasn't able to see, or felt liike I would pass out and it would get even worse. So I would lay on my side with a wet cloth on my face, it would eventually stop for the moment. But it still kept happening to me until I gave birth. I will never be pregnant again now. Good luck!
