I'm experiencing this too. On Thursday and Friday at work, I got very light-headed, sweaty, dizzy, and nauseous. I talked with my doctor about it and he said it is normal and to make sure you are eating frequent, small meals and to sit down and relax the minute it happens.
It can be a number of things... for me when I'm dehydrated i get dizzy and for a while, before I realized I was anemic I would get dizzy if I hadn't had enough iron. Talk to your doc/midwife and I am sure they can help!
Yes, I've been getting dizzy more and more lately. Also nauseous. I think it all has to do with dehydration. The further along I get, the more dehydrated I get. I feel like I drink soooo much water, but at this stage you can't really drink too much.
