Ever since I found out I was pregnant and started feeling really nauseous, I almost have this feeling like I am going to passout too. I get really light headed almost and if I get up too fast, I get dizzy for a few seconds. I heard that it could be because of dehydration or anemia but I can't see a doctor for another few weeks. Pretty much when I start feeling less nauseous, I start to feel more lightheaded. Has anyone else had this feeling? And what did it turn out to be? Did anything help?
