This is my third pregnancy and I've had fainting spells with my previous two nor while not pregnant. However, recently, I started to blacked out and sat myself quickly to the floor so i wouldn't hit hard and slowly began to recover. I didn't completely faint but did lose control and was sweaty on my neck even in air conditioning during the episode. It was a different feeling from being light headed or dizzy(i have experienced those but not this pregnancy) and scared me to death. I called my doctor and he said its normal as long as it doesn't continue and could of been caused by dehydration, anemia, or overexerting myself causing my body to overheat and that i should be mindful of my water intake, iron intake, my physical activity, and body temperature so if it happens again, I can pin point the cause. Has anyone else experienced fainting?
