I am 13 weeks today and have been noticing (the past two days) that I am pretty dizzy, lightheaded and hot. Admittedly, I have been going longer without eating and I haven't been drinking as much water. I know this seems like a bone headed "duh!!!" kind of post but not drinking as much water wouldn't have been abnormal pre-pregnancy. So, is it "normal" to get dizzy during pregnancy?
